DM74ALS245AWM集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF中文资料

General Description

This advanced low power Schottky device contains 8 pairs of 3-STATE logic elements configured as octal bus transceivers. These circuits are designed for use in memory, microprocessor systems and in asynchronous bidirectional data buses.

特性 Features

■ Advanced oxide-isolated, ion-implanted Schottky TTL process

■ Non-inverting logic output

■ Glitch free bus during power up and down

■ 3-STATE outputs independently controlled on A and B buses

■ Low output impedance to drive terminated transmission lines to 133Ω

■ Switching response specified into 500Ω/50 pF

■ Specified to interface with CMOS at VOH = VCC − 2V

■ PNP inputs to reduce input loading

■ Switching specifications guaranteed over full temperature and VCC range
