74HC/HCT563
General description
The 74HC/HCT563 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.
The 74HC/HCT563 are octal D-type transparent latches featuring separate D-type inputs for each latch and inverting 3-state outputs for bus oriented applications.
A latch enable (LE) input and an output enable (OE) input are common to all latches.
The '563' is functionally identical to the '573', but has inverted outputs.
The '563' consists of eight D-type transparent latches with 3-state inverting outputs. The LE and OE are common to all latches.
When LE is HIGH, data at the Dn inputs enter the latches. In this condition the latches are transparent, i.e. a latch output will change state each time its corresponding D-input changes.
When LE is LOW the latches store the information that was present at the D-inputs a set-up time preceding the HIGH-to-LOW transition of LE.
When OE is LOW, the contents of the 8 latches are available at the outputs. When OE is HIGH, the outputs go to the high impedance OFF-state.
Operation of the OE input does not affect the state of the latches.
Features
- 3-state inverting outputs for bus oriented applications
- Inputs and outputs on opposite sides of package allowing easy interface with microprocessor
- Common 3-state output enable input
- Output capability: bus driver
- ICC category: MSI
