MC74HCT541A

Octal 3-State Non-Inverting Buffer/Line Driver/Line Receiver With LSTTL-Compatible Inputs

ON Semiconductor 

MC74HCT541A

PIN DESCRIPTIONS

INPUTS

A1, A2, A3, A4, A5, A6, A7, A8 (PINS 2, 3, 4, 5, 6, 7, 8,

9) — Data input pins. Data on these pins appear in

non–inverted form on the corresponding Y outputs, when

the outputs are enabled.

CONTROLS

OE1, OE2 (PINS 1, 19) — Output enables (active–low).

When a low voltage is applied to both of these pins, the

outputs are enabled and the device functions as a

non–inverting buffer. When a high voltage is applied to

either input, the outputs assume the high impedance state.

OUTPUTS

Y1, Y2, Y3, Y4, Y5, Y6, Y7, Y8 (PINS 18, 17, 16, 15, 14,

13, 12, 11) — Device outputs. Depending upon the state of

the output enable pins, these outputs are either

non–inverting outputs or high–impedance outputs.
