74系列逻辑芯片/74HCT573D
GENERAL DESCRIPTION
The 74HC/HCT573 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/HCT573 are octal D-type transparent latches featuring separate D-type inputs for each latch and 3-state outputs for bus oriented applications.
A latch enable LE input and an output enable OE input are common to all latches.
FEATURES
• Inputs and outputs on opposite sides of package allowing easy interface with microprocessors
• Useful as input or output port for microprocessors/microcomputers
• 3-state non-inverting outputs for bus oriented applications
• Common 3-state output enable input
• Functionally identical to the “563” and “373”
• Output capability: bus driver
• ICCcategory: MSI
