Nine wide Schmitt trigger buffer/line driver 74HC/HCT9015
FEATURES
• Schmitt trigger action on all data inputs
• Output capability: standard
• ICCcategory: MSI
The 74HC/HCT9015 are nine wide Schmitt trigger
buffer/line drivers with Schmitt trigger inputs. These inputs
transform slowly changing input signals into sharply
defined jitter-free output signals.
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.
