Nine wide Schmitt trigger buffer/line driver

Product specification

74HC/HCT9015

FEATURES

• Schmitt trigger action on all data inputs

• Output capability: standard

• ICC category: MSI

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.

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.

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
