MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC74HC237 1-of-8 Decoder/Demultiplexer with Address Latch High–Performance Silicon–Gate CMOS N SUFFIX PLASTIC PACKAGE 16 The MC74HC237 is identical in pinout to the LS137, but has noninverting CASE 648–08 outputs. The device inputs are compatible with standard CMOS outputs; with 1 pullup resistors, they are compatible with LSTTL outputs. The HC237 decodes a three–bit Address to one–of–eight active–high D SUFFIX outputs. The device has a transparent latch for storage of the Address. Two 16 SOIC PACKAGE Chip Selects, one active–low and one active–high, are provided to facilitate CASE 751B–05 1 the demultiplexing, cascading, and chip–selecting functions. The demultiplexing function is accomplished by using the Address inputs to selec
