MC74HC540A
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 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 an inverter. 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 inverting outputs or
high−impedance outputs.
