Product speciﬁcation

Nine wide Schmitt trigger buffer/line

driver; inverting

74HC/HCT9014

FEATURES

• Schmitt trigger action on all data inputs

• Output capability: standard

• ICC category: MSI

GENERAL DESCRIPTION

The 74HC/HCT9014 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/HCT9014 are nine wide Schmitt trigger

inverting buffer/line drivers with Schmitt trigger inputs.

These inputs transform slowly changing input signals into

sharply defined jitter-free output signals.

The “9014” is identical to the “9015” but has inverting

inputs.

QUICK REFERENCE DATA

GND = 0 V; Tamb =25 °C; tr =tf = 6 ns

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
