REJ03D0593–0200

(Previous ADE-205-470)

Rev.2.00

Jan 31, 2006

Description

The HD74HC238 has 3 binary select inputs (A, B and C). If the device is enabled these inputs determine 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(Data to Y) = 15 ns typ (C_L= 50 pF)

High Output Current: Fanout of 10 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)
