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)
