ON MC74HCT541AFG Octal 3-state non-inverting buffer/line driver/line receiver with lsttl-compatible input Datasheet

MC74HCT541A
Octal 3-State Non-Inverting
Buffer/Line Driver/
Line Receiver With
LSTTL-Compatible Inputs
http://onsemi.com
High−Performance Silicon−Gate CMOS
The MC74HCT541A is identical in pinout to the LS541. This
device may be used as a level converter for interfacing TTL or NMOS
outputs to high speed CMOS inputs.
The HCT541A is an octal non−inverting buffer/line driver/line
receiver designed to be used with 3−state memory address drivers,
clock drivers, and other bus−oriented systems. This device features
inputs and outputs on opposite sides of the package and two ANDed
active−low output enables.

This device contains protection
circuitry to guard against damage due
to high static voltages or electric
fields. However, precautions must be
taken to avoid applications of any
voltage higher than maximum rated
voltages to this high−impedance
circuit. For proper operation, Vin and
Vout should be constrained to the
range GND v (Vin or Vout) v VCC.
Unused inputs must always be tied
to an appropriate logic voltage level
(e.g., either GND or VCC). Unused
outputs must be left open.

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.
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.
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.
