Description

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.
