Quad 2-input NAND gate
Product specification
74HC/HCT03
FEATURES
• Level shift capability
• Output capability: standard (open drain)
• ICC category: SSI
GENERAL DESCRIPTION
The 74HC/HCT03 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/HCT03 provide the 2-input NAND function.
The 74HC/HCT03 have open-drain N-transistor outputs,
which are not clamped by a diode connected to VCC. In
the OFF-state, i.e. when one input is LOW, the output
may be pulled to any voltage between GND and VOmax.
This allows the device to be used as a LOW-to-HIGH or
HIGH-to-LOW level shifter. For digital operation and
OR-tied output applications, these devices must have a
pull-up resistor to establish a logic HIGH level.

Notes
1. CPD is used to determine the dynamic power dissipation (PD in µW):
PD = CPD × VCC2× fi + ∑ (CL × VCC2 × fo) + ∑ (VO2/RL) × duty factor LOW, where:
fi = input frequency in MHz
fo = output frequency in MHz
VO = output voltage in V
CL = output load capacitance in pF
VCC = supply voltage in V
RL = pull-up resistor in MΩ
∑ (CL × VCC2 × fo) = sum of outputs
∑ (VO2/RL) = 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
3. The given value of CPD is obtained with:
CL = 0 pF and RL = ∞
