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)
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
VOmax. This allows the device to be used as a
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.
• ICC category: MSI
GENERAL DESCRIPTION
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.
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
