Product specification
Nine wide Schmitt trigger buffer;
open drain outputs
74HC/HCT9115
The Schmitt trigger action in the data inputs transform
slowly changing input signals into sharply defined
jitter-free output signals.
FEATURES
• Schmitt trigger action on all data inputs
• Output capability: standard (open drain)
• ICC category: MSI
The 74HC/HCT9115 have open-drain N-transistor
outputs, which are not clamped by a diode connected to
VCC. In the OFF-state, i.e. when one input is HIGH, the
output may be pulled to any voltage between GND and
GENERAL DESCRIPTION

Omax. This allows the device to be used as a
The 74HC/HCT9115 are high-speed Si-gate CMOS
devices and are pin compatible with low power Schottky
TTL (LSTTL). They are specified in compliance with
JEDEC standard no. 7A.
LOW-to-HIGH or HIGH-to-LOW level shifter. For digital
operation and OR-tied output applications, these devices
must have a pull-up resistor to establish a logic HIGH level.
The “9115” is identical to the “9114” but has non-inverting
outputs.
The 74HC/HCT9115 are nine wide Schmitt trigger buffer
with open drain outputs and Schmitt trigger inputs.

Notes
1. CPD is used to determine the dynamic power dissipation (PD in µW):
PD = CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where:
fi = input frequency in MHz
fo = output frequency in MHz
∑ (CL × VCC2 × fo) = sum of outputs
CL = output load capacitance in pF
VCC = supply voltage in V
2. For HC the condition is VI = GND to VCC
For HCT the condition is VI = GND to VCC − 1.5 V
