HEF40244B
Octal buffers with 3-state outputs
Rev. 4 — 29 June 2018
Product data sheet
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
