74F647 Overview
Key Specifications
Package: DIP
Operating Voltage: 5 V
Max Voltage (typical range): 5.5 V
Min Voltage (typical range): 4.5 V
Description
The 74F647 and 74F649 Transceivers/Registers consist of bus transceiver circuits with open-collector outputs, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or from the internal registers. Data on the A or B bus will be clocked into the registers as the appropriate clock pin goes to a High logic level.
Key Features
- High impedance NPN base inputs for reduced loading (20µA in High and Low states)
- Independent registers for A and B buses
- Multiplexed real-time and stored data
- Choice of non-inverting and inverting data paths
- Open Collector outputs
