Product Summary
The MM74HCT245WMX-N 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 of MM74HCT245WMX-N possesses the low power consumption of CMOS circuitry, yet has speeds comparable to low power Schottky TTL circuits. The MM74HCT245WMX-N 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.
