Description

The TIL311 is a single-digit LED hexadecimal display with internal four-bit latch, decoder, and constant-currentLED drivers in a 14-pin dual-in-line-package. Hexadecimal characters are formed by a 4 × 7 array of redlight-emitting-diodes that are illuminated in a modified seven-segment configuration. The device includesright-hand and left-hand externally driven decimal points.

DESCRIPTION

Blanking Input. When high, the display is blanked regardless of the levels of the other inputs. When low,a character is displayed as determined by the data in the latches. The blanking input may be pulsed forintensity modulation.

Latch Data Input A. Data on this input is entered into the latch when the Latch Strobe Input is low. Thebinary weight of this input is 1.

Latch Data Input B. Data on this input is entered into the latch when the Latch Strobe Input is low. Thebinary weight of this input is 2.

Latch Data Input C. Data on this input is entered into the latch when the Latch Strobe Input is low. Thebinary weight of this input is 4.

Latch Data Input D. Data on this input is entered into the latch when the Latch Strobe Input is low. Thebinary weight of this input is 8.

Common Ground. This is the negative terminal for all logic and LED currents except for the decimal points.LED Supply (VCC). This terminal permits the user to save on regulated VCC current by using a separateLED supply, or it may be externally connected to the logic supply (VCC).

Left Decimal Point Cathode. This LED is not connected to the logic chip. If a decimal point is used, anexternal resistor or other current-limiting mechanism must be connected in series with it.Logic Supply (VCC). Separate VCC terminal for the logic chip.There is no pin at this location.

Right Decimal Point Cathode. This LED is not connected to the logic chip. If a decimal point is used, anexternal resistor or other current-limiting mechanism must be connected in series with it.I

Latch Strobe Input. When low, the data in the latches follow the data on the latch data inputs. When high,the data in the latches does not change. If the display is blanked and then restored while this input is high,the previously displayed character will again be displayed.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, andfunctional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is notimplied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES:1.All voltages are with respect to the Common Ground terminal.

2.Case temperature is the surface temperature of the plastic measured directly over the integrated circuit. Forced-air cooling may be

required to maintain this temperature.

TAOS058 − OCTOBER 2007PRINCIPLES OF OPERATION

TTL-level four-bit binary data is applied to Latch Data Inputs A through D. As long as the Latch Strobe Input islow, latch output follows the input data. Latch output data is decoded and sent to the display LEDs to form thecorresponding characters. When the Latch Strobe Input goes high, input data is stored in the latch and thedisplay does not change.

The resulting character displays for the values of the binary data in the latch are shown in Figure 4.

01234567101112131415

Figure 4. Display Character Configurations

While the Blanking Input is held low, the display shows the character corresponding to the data at the latchoutput. When the Blanking Input goes high, drive to the character display LEDs is removed and the display isblanked (except for the decimal points, which are independent and externally driven). Data in the latch andoperation of the device logic elements are not affected by blanking the display. A repetitive variable-width pulsecan be applied to the Blanking Input to adjust the apparent brightness of the display.

The LED driver outputs are designed to maintain a relatively constant on-level current of approximately 5 mAthrough each LED that forms the hexadecimal character. This current is virtually independent of the LED supplyvoltage within the recommended operating conditions. Drive current varies slightly with changes in the logicsupply voltage, resulting in a change in luminous intensity as shown in Figure 2. This change is not noticeableto the eye.

The decimal point anodes are connected to the LED supply; the cathodes are connected to external pins. Sincethere is no current limiting built into the decimal point circuits, current limiting must be provided externally if thedecimal points are used.
