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.
