74HC/HCT9015
The 74HC/HCT9015 are nine wide Schmitt trigger
FEATURES
buffer/line drivers with Schmitt trigger inputs. These inputs
transform slowly changing input signals into sharply
defined jitter-free output signals.
• Schmitt trigger action on all data inputs
• Output capability: standard
• ICC category: MSI
The “9015” is identical to the “9014” but has non-inverting
inputs.
GENERAL DESCRIPTION
The 74HC/HCT9015 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.

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
V
CC = 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

DC CHARACTERISTICS FOR 74HCT
For the DC characteristics see “74HC/HCT/HCU/HCMOS Logic Family Specifications”.
Transfer characteristics are given below.
Output capability: standard
ICC category: MSI
Note to HCT types
The value of additional quiescent supply current (∆ICC) for a unit load of 1 is given in the family specifications.
To determine ∆ICC per input, multiply this value by the unit load coefficient shown in the table below.
