1. General description
The HEF40240B is an octal inverting buffer with 3-state outputs. It features output stages
with high current output capability suitable for driving highly capacitive loads.
The 3-state outputs are controlled by the output enable inputs nOE. A HIGH on nOE
causes the outputs to assume a high-impedance OFF-state. The device also features
hysteresis on all inputs to improve noise immunity. Schmitt-trigger action makes the inputs
highly tolerant to slow input rise and fall times.
The HEF40240B is pin and functionally compatible with the TTL ‘240’ device.
It operates over a recommended V
DD
power supply range of 3 V to 15 V referenced to V
SS
(usually ground). Unused inputs must be connected to V
DD
, V
SS
, or another input. It is
also suitable for use over the full industrial (
40
