Datasheet Details

Part number	HD74HC243
Manufacturer	Hitachi Semiconductor (now Renesas)
File Size	60.31 KB
Description	Quad. Bus Transceivers (with 3-state outputs)/Quad. Bus Transceivers (with noninverted 3-state outputs)
Datasheet	HD74HC243_HitachiSemiconductor.pdf

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.

High Speed Operation: tpd = 10 ns typ (CL = 50 pF) High Output Current: Fanout of 15 LSTTL Loads Wide Operating Voltage: VCC = 2 to 6 V Low Input Current: 1 µA max Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) Function Table HD74HC242 Control inputs GAB H L H L I O O Z : : : : GBA H H L L Input Output Inverting Output Hight Impedance Data Port Status A O Z Z I B I Z Z O HC74HC243 Data Port Status A O Z Z I B I Z Z O HD74HC24.
