-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 ’HC540 and CD74HCT540 are Inverting Octal Buffers and Line Drivers with Three-State Outputs and the capability to drive 15 LSTTL loads.
The ’HC541 and ’HCT541 are NonInverting Octal Buffers and Line Drivers with Three-State Outputs that can drive 15 LSTTL loads.
The Output Enables (OE1) and (OE2) control the Three-State Outputs.
If either OE1 or OE2 is HIGH the outputs will be in the high impedance state.
For data output OE1 and OE2 both must be LOW.
