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.
Features
• LSTTL Output Logic Level Compatibility as well as CMOS Output Compatibility
• High Speed Operation: tpd (A to Y) = 9.5 ns typ (CL = 50 pF)
• High Output Current: Fanout of 15 LSTTL Loads
• Wide Operating Voltage: VCC = 4.5 to 5.5 V
• Low Input Current: 1 µA max
• Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)
