Features
Description
Three-State Outputs
Separate Output Enable Inputs
Fanout (Over Temperature Range) - Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads - Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads
Wide Operating Temperature Range . . . -55oC to 125oC
Balanced Propagation Delay and Transition Times
Significant Power Reduction Compared to LSTTL Logic ICs
HC Types - 2V to 6V Operation - High Noise Immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V
HCT Types - 4.5V to 5.5V Operation - Direct LSTTL Input Logic Compatibility, VIL= 0.8V (Max), VIH = 2V (Min) - CMOS Input Compatibility, Il ≤ 1µA at VOL, VOH
The ’HC125 and ’HCT125 contain 4 independent three-state buffers, each having its own output enable input, which when “HIGH” puts the output in the high impedance state.
