SN54ALS563B Overview
Key Specifications
Package: CDIP
Mount Type: Through Hole
Pins: 20
Operating Voltage: 5 V
Key Features
- 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads
- They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers
- While the latch-enable (LE) input is high, the Q outputs follow the complements of data (D) inputs
- When LE is taken low, the outputs are latched at the inverse of the levels set up at the D inputs
- In the high-impedance state, the outputs neither load nor drive the bus lines significantly
