Overview

HD74HC242/HD74HC243 Quad.
Bus Transceivers (with 3-state outputs) Quad.
Bus Transceivers (with noninverted 3-state outputs) Description The HD74HC242 is an inverting buffer and the HD74HC243 is a noninverting buffer.
Each device has one active high enable (GBA), and one active low enable ( GAB).
GBA enables the A output and GAB enables the B outputs.
The device does not have schmitt trigger inputs.
