6.9-mm (0.270-Inch) Character Height High Luminous Intensity TIL306 Has Left Decimal TIL307 Has Right Decimal Easy System Interface.

Wide Viewing Angle Internal TTL MSI Chip and Counter, Latch, Decoder, and Driver Constant-Current Drive for Light-Emitting Diodes.

These assemblies consist of display chips and a TTL MSI chip mounted on a header with a red molded plastic body. Multiple displays may be mounted 11,43-mm (0.450-inch) centers.

PRODUCTION DATA information is current as of publication date. Products conform to specifications per the terms of Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters.

These internally-driven seven-segment light-emitting-diode (LED) displays contain a BCD counter, a four-bit latch, and a decoder/LED driver in a single 16-pin package. A description of the functions of the inputs and outputs of these devices are in the terminal function table. The TTL MSI circuits contain the equivalent of 86 gates on a single chip. Logic inputs and outputs are completely TTL/DTL compatible. The buffered inputs are implemented with relatively large resistors in series with the bases of the input transistors to lower drive-current requirements to one-half of that required for a standard Series 54/74 TTL input. The serial-carry input, actually two internal loads, is rated as one standard series 54/74 load. The logic outputs, except RBO, are active pullup, and the latch outputs QA, QB, QC, and QD are each capable of driving three standard Series 54/74 loads at a low logic level or six loads at a high logic level while the maximum-count output is capable of driving five Series 54/74 loads at a low logic level or ten loads at a high logic level. The RBO node with passive pull-up serves as a ripple-blanking output with the capability to drive three Series 54/74 loads. The LED driver outputs are designed specifically to maintain a relatively constant on-level current of approximately 7 mA through each LED segment and decimal point. All inputs are diode clamped to minimize transmission-line effects, thereby simplifying system design. Maximum clock frequency is typically 18 MHz and power dissipation is typically 600 mW with all segments on.

NOTES:

- Lead dimensions are not controlled above the seating plane.

- Centerlines of character segments and decimal points are shown as dashed lines. Associated dimensions are nominal.

- The true-position pin spacing mm (0.100 inch) between centerlines. Each centerline is located with mm (0.010 inch) of its true longitudinal position relative to pins 1 and 16.
