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.

2 Features and benefits

• Octal bus interface

• 3-state buffers

• Fully static operation

• 5 V, 10 V, and 15 V parametric ratings

• Standardized symmetrical output characteristics

• Specified from −40 °C to +85 °C
