3-to-8-line Decoder/Demultiplexer

REJ03D0661–0200

(Previous ADE-205-549)

Rev.2.00

Mar 30, 2006

Description

The HD74HCT238 has 3 binary select inputs (A, B, and C). If the device is enabled these inputs determined which one

of the eight normally high outputs will go low. Two active low and one active high enables (G₁, G_2Aand G_2B) are

provided to ease the cascading of decoders.

Features

•

High Speed Operation: t_pd(A, B, C to Y) = 16.5 ns typ (C_L= 50 pF)

High Output Current: Fanout of 10 LSTTL Loads

Wide Operating Voltage: V_CC= 2 V to 6 V

Low Input Current: 1 µA max

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