Overview
The 74HC237D-Q100118 is a high-speed CMOS 3-to-8 decoder/address latch integrated circuit manufactured by NXP USA Inc. This device is fabricated using silicon gate C2MOS technology, which provides high-speed operation similar to LSTTL while maintaining the low power dissipation characteristic of CMOS technology. The 74HC237D-Q100118 is designed to decode 3-bit binary data and select one of eight output lines based on this data. It features a common GL enable input and two additional enable inputs (G1 and G2) to facilitate cascade connections and applications in memory systems.
