MM74HC245ANX规格书详情
General Description
The MM74HC245A 3-STATE bidirectional buffer utilizes advanced silicon-gate CMOS technology, and is intended for two-way asynchronous communication between data buses. It has high drive current outputs which enable high speed operation even when driving large bus capacitances. This circuit possesses the low power consumption and high noise immunity usually associated with CMOS circuitry, yet has speeds comparable to low power Schottky TTL circuits.
This device has an active LOW enable input G and a direction control input, DIR. When DIR is HIGH, data flows from the A inputs to the B outputs. When DIR is LOW, data flows from the B inputs to the A outputs. The MM74HC245A transfers true data from one bus to the other. This device can drive up to 15 LS-TTL Loads, and does not have Schmitt trigger inputs. All inputs are protected from damage due to static discharge by diodes to VCC and ground.
Features
■ Typical propagation delay: 13 ns
■ Wide power supply range: 2–6V
■ Low quiescent current: 80 μA maximum (74 HC)
■ 3-STATE outputs for connection to bus oriented systems
■ High output drive: 6 mA (minimum)
■ Same as the 645
