Overview

HD74HCT242/HD74HCT243 Quad.
Bus Transceivers (with 3-state outputs) Description The HD74HCT242 is an inverting buffer and the HD74HCT243 is a noninverting 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.
The device does not have schmitt trigger inputs.
