This data sheet introduces the Philips Semiconductors HEF4085B dual 2-wide 2-input AND-OR-invert gate's functions, features and specifications.
This document is a product specification datasheet for the Philips HEF4085B integrated circuit. The device is a dual 2-wide 2-input AND-OR-invert gate, where each gate includes an additional input that can function as either an expander or an inhibit input. The outputs are fully buffered to ensure high noise immunity and pattern insensitivity of the output impedance.
| Product Type | Dual 2-wide 2-input AND-OR-invert gate |
|---|---|
| Output Transition Time (HIGH to LOW) | Max 60 ns (typical 10 ns) |
| Output Transition Time (LOW to HIGH) | Max 60 ns (typical 6 ns) |
The additional input (Aq or By) can be used as either an expander input or an inhibit input.
It is a dual 2-wide 2-input AND-OR-invert gate.
The output (Oa or Os) is forced LOW independent of the other inputs.
The maximum delay is 60 ns.
