Inverting Quad TRI-STATE Transceiver

These TRI-STATE bidirectional inverting and non-inverting Buffers utilize advanced silicon-gate CMOS technology and are intended for two-way asynchronous Communication be- tween data buses. They have high drive current outputs which enable high speed operation when driving large bus capacitances. These circuits possess the low power dissi- pation and high noise immunity associated with CMOS cir- cuits, but speeds comparable to low power Schottky TTL circuits. They CAN also drive 15 LS-TTL loads. The MM54HC243/MM74HC243 is a non-inverting Buffer and the MM54HC242 MM74HC242 is an inverting Buffer Each device has one active high enable (GBA), and one active low enable (GAB). GBA enables the A outputs and GAB enables the B outputs. This device does not have Schmitt Trigger inputs By National Semiconductor Corporation
