1. General description
The HEF40098B is a hex inverting buffer with 3-state outputs. The 3-state outputs are
controlled by two active LOW enable inputs (1OE
and 2OE). A HIGH on 1OE causes four
of the six active LOW buffer elements (1Y
0 to 1Y3) to assume a high-impedance or
OFF-state regardless of the other input conditions and a HIGH on 2OE
causes the outputs
of the remaining two buffer elements (2Y
0 and 2Y1) to assume a high-impedance or
OFF-state regardless of the other input conditions.
It operates over a recommended V
DD
power supply range of 3 V to 15 V referenced to V
SS
(usually ground). Unused inputs must be connected to V
DD
, V
SS
, or another input.
2. Features and benefits

5 V, 10 V, and 15 V parametric ratings
Standardized symmetrical output characteristics
Specified from 40 C to +85 C
Complies with JEDEC standard JESD 13-B
