MM74HCT245 Octal 3-STATE Transceiver February 1984 Revised February 1999 MM74HCT245 Octal 3-STATE Transceiver General Description The MM74HCT245 3-STATE bi-directional 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 of CMOS circuitry, yet has speeds comparable to low power Schottky TTL circuits. This device is TTL input compatible and can drive up to 15 LS-TTL loads, and all inputs are protected from damage due to static discharge by diodes to VCC and ground. The MM74HCT245 has one active low enable input (G), and a direction control (DIR).
