Nine input lines are encoded to a four line BCD output.
The implied decimal zero condition requires no input condition as zero is encoded when all nine data lines are at a high logic level.
All data inputs and outputs are active at the low logic level.
Features • High Speed Operation: tpd = 14.
5 ns typ (CL = 50 pF) • High Output Current: Fanout of 10 LSTTL Loads • Wide Operating Voltage: VCC = 2 to 6 V • Low Input Current: 1 µA max • Low Quiescent Supply Current: ...
