74HC9115
Nine wide Schmitt trigger buffer; open drain outputs
Rev. 3 — 10 April 2018
Product data sheet
1
General description
The 74HC9115 is a 9-bit buffer with Schmitt trigger inputs and open drain outputs. Inputs
include clamp diodes. This enables the use of current limiting resistors to interface inputs
to voltages in excess of V
CC
. Schmitt trigger inputs transform slowly changing input
signals into sharply defined jitter-free output signals.
