74HC/HCT20
FEATURES
• Output capability: standard
• ICC category: SSI
GENERAL DESCRIPTION
The 74HC/HCT20 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/HCT20 provide the 4-input NAND function.

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 = output load capacitance in pF
VCC = supply voltage in V
∑ (CL × VCC2 × fo) = sum of outputs
2. For HC the condition is VI = GND to VCC
For HCT the condition is VI = GND to VCC − 1.5 V

For the DC characteristics see “74HC/HCT/HCU/HCMOS Logic Family Specifications”.
Output capability: standard
ICC category: SSI
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.
