• Fanout (Over Temperature Range)
- Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads
- Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads
• Wide Operating Temperature Range . . . -55^oC to 125^oC
• Balanced Propagation Delay and Transition Times
• Significant Power Reduction Compared to LSTTL
Logic ICs
• HC Types
- 2V to 6V Operation
- High Noise Immunity: N_IL = 30%, N_IH = 30% of V_CC
at V_CC = 5V
• HCT Types
- 4.5V to 5.5V Operation
- Direct LSTTL Input Logic Compatibility,
V_IL= 0.8V (Max), V_IH = 2V (Min)
- CMOS Input Compatibility, I_l ≤ 1µA at V_OL, V_OH
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 Non-
Inverting Octal Buffers and Line Drivers with Three-State Out-
puts 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 imped-
ance state. For data output OE1 and OE2 both must be LOW.
