HD74HCT240
Octal Buffers/Line Drivers/Line Receivers
(with inverted 3-state outputs)
Description
The HD74HCT240 is an inverting buffer and has two active low enables (1G and 2G). Each enable
independently controls 4 buffers. This 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) = 11 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)
