HD74HC354
8-to-1-line Data Selectors/Multiplexer Register
(with 3-state outputs)
Description
This data selectors/multiplexers contains full on-chip binary decoding to select one of eight data sources.
The data select address is stored in transparent latches that are enabled by a low level address on pin 11,
Select Control. Data on the 8 input lines is stored in a parallel input/output register which in the
HD74HC354 is composed of 8 transparent latches enabled by a low level on pin 9, Data Control. Both true
(Y) and complementary (W) 3-state outputs are available.
Features
• High Speed Operation: tpd (DC to W, Y) = 23 ns typ (CL = 50 pF)
• High Output Current: Fanout of 15 LSTTL Loads
• Wide Operating Voltage: VCC = 2 to 6 V
• Low Input Current: 1 µA max
• Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)
