HEF40098B
Hex inverting buffer; 3-state
Rev. 8 — 21 November 2011
Product data sheet
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 (1Y0 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 (2Y0 and 2Y1) to assume a high-impedance or
OFF-state regardless of the other input conditions.
It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS
(usually ground). Unused inputs must be connected to VDD, VSS, or another input.
2. Features and benefits

5 V, 10 V, and 15 V parametric ratings
