74HC646 Overview
The 74HC/HCT646 are high-speed Si-gate CMOS devices and are pin patible with low power Schottky TTL (LSTTL). They are specified in pliance with JEDEC standard no. The 74HC/HCT646 consist of bus transceiver circuits with 3-state outputs, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the internal registers.
74HC646 Key Features
- Independent register for A and B buses
- Multiplexed real-time and stored data
- Output capability: bus driver
