HD74HC243 Datasheet | Hitachi Semiconductor

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.
