CD74HC541 and CD74HCT541 are Non-Inverting Octal Buff-

ers and Line Drivers with Three-State Outputs that can drive

15 LSTTL loads. The Output Enables (OE1) and (OE2) con-

trol 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.
