Quad 2-input NAND gate
Philips Semiconductors Product specification
Quad 2-input NAND gate 74HC/HCT03
FEATURES Level shift capability Output capability: standard (open drain) ICC category: SSI
GENERAL DESCRIPTIONThe 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.
QUICK REFERENCE DATAGND= 0 V; Tamb =25 °C; tr =tf= 6 ns
Notes CPD is used to determine the dynamic power dissipation (PD in μW): =CPD × VCC2× fi+∑ (CL× VCC2 × fo) + ∑ (VO2 /RL) × duty factor LOW, where:= input frequency in MHz= output frequency in MHz= output voltage in V= output load capacitance in pF
VCC= supply voltage in V= pull-up resistor in MΩ
∑ (CL × VCC2 × fo)= sum of outputs
∑ (VO2 /RL)= sum of outputs For HC the condition is VI= GND to VCC
For HCT the condition is VI= GND to VCC − 1.5 V The given value of CPD is obtained with:= 0 pF and RL=∞
