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.
