MC74HC03A
Quad 2−Input NAND Gate
with Open−Drain Outputs
High−Performance Silicon−Gate CMOS
The MC74HC03A is identical in pinout to the LS03. The device
inputs are compatible with Standard CMOS outputs; with pullup
resistors, they are compatible with LSTTL outputs.
The HC03A NAND gate has, as its outputs, a high−performance
MOS N−Channel transistor. This NAND gate can, therefore, with a
suitable pullup resistor, be used in wired−AND applications. Having
the output characteristic curves given in this data sheet, this device can
be used as an LED driver or in any other application that only requires
a sinking current.
• Output Drive Capability: 10 LSTTL Loads With Suitable Pullup
Resistor
• Outputs Directly Interface to CMOS, NMOS and TTL
• High Noise Immunity Characteristic of CMOS Devices
• Operating Voltage Range: 2 to 6V
• Low Input Current: 1µA
• In Compliance With the JEDEC Standard No. 7A Requirements
• Chip Complexity: 28 FETs or 7 Equivalent Gates

This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high−impedance circuit. For proper operation, Vin and
Vout should be constrained to the
range GND (Vin or Vout) VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.
