A20143 - MM74HCT245N Octal 3-State Transceiver (National)
The MM74HCT245N 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 MM74HCT245N has one active low enable input (G), and a direction control (DIR). When the DIR input is HIGH, data flows from the A inputs to the B outputs. When DIR is LOW, data flows from B to A.
MM74HCT devices are intended to interface between TTL and NMOS components and standard CMOS devices. These parts are also plug-in replacements for LS-TTL devices and can be used to reduce power consumption in existing designs.
Features:
TTL input compatible
3-State outputs for connection to system busses
High output drive current: 6 mA (min)
High speed: 16 ns typical propagation delay
Low power: 80 mA (74HCT Series)
20 pin DIP. Manufactured by National.
