信息

The MM74HC245 is a Octal 3-STATE Transceiver The MM74HC245 3-STATE bidirectional buffer utilizesadvanced silicon-gate CMOS technology, and is intendedfor two-way asynchronous communication between databuses. It has high drive current outputs which enable highspeed operation even when driving large bus capaci-tances. This circuit possesses the low power consumptionand high noise immunity usually associated with CMOS cir-cuitry, yet has speeds comparable to low power SchottkyTTL circuits This device has an active LOW enable input G and a direction control input, DIR. When DIR is HIGH, data flows fromthe A inputs to the B outputs. When DIR is LOW, data flowsfrom the B inputs to the A outputs. The MM74HC245transfers true data from one bus to the othe This device can drive up to 15 LS-TTL Loads, and does nothave Schmitt trigger inputs. All inputs are protected fromdamage due to static discharge by diodes to VCC and ground
