HEF40106B
Hex inverting Schmitt trigger
Rev. 7 — 21 November 2011
Product data sheet
1. General description
The HEF40106B provides six inverting buffers. Each input has a Schmitt trigger circuit.
The inverting buffer switches at different points for positive-going and negative-going
signals. The difference between the positive voltage (V
T+
) and the negative voltage (V
T
)
is defined as hysteresis voltage (V
H
).
The HEF40106B may be used for enhanced noise immunity or to “square up” slowly
changing waveforms.
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.
