1 General description

The HEF40244B is an octal non-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 EOA and EOB. A HIGH

on EOA or EOB 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 in the inputs makes the circuit highly tolerant to slower input rise

and fall times.
