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: t_pd(DC to W, Y) = 23 ns typ (C_L= 50 pF)

High Output Current: Fanout of 15 LSTTL Loads

Wide Operating Voltage: V_CC= 2 to 6 V

Low Input Current: 1 µA max

Low Quiescent Supply Current: I_CC(static) = 4 µA max (Ta = 25°C)
