High-Speed CMOS Logic
Octal Buffer and Line Drivers, Three-State
Features
Description
• ’HC540, CD74HCT540 . . . . . . . . . . . . . . . . . . . Inverting
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.
• ’HC541, ’HCT541 . . . . . . . . . . . . . . . . . . . . . . Non-Inverting
• Buffered Inputs
• Three-State Outputs
• Bus Line Driving Capability
• Typical Propagation Delay = 9ns at VCC = 5V,
CL = 15pF, TA = 25oC
Ordering Information
• Fanout (Over Temperature Range)
- Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads
- Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads
