MC14572UBCP Hex Gate IC DIP-16
The MC14572UB is a compact CMOS logic IC that integrates six functional gates on one monolithic chip: four independent inverters plus one NOR and one NAND gate. Its internal design uses complementary P-channel and N-channel MOS enhancement devices arranged so the chip delivers standard logic functions while minimizing static power draw. The gate outputs and inputs are arranged for convenient wiring between functions, making simple combinational logic arrangements straightforward inside small boards.
Designed as a general-purpose logic building block, the IC emphasizes very low quiescent current and robust noise immunity. Because the device is CMOS, it naturally exhibits high input impedance and low static current, while the gate-level layout and pin adjacency simplify using some gates as inverters or combining outputs with nearby inputs without long PCB traces. The internal protection helps the device tolerate standard handling and system environments.
Mechanically offered in a 16-pin package, the device is intended to be used where compact, low-power logic is needed. Designers should tie unused inputs to a defined rail, observe the device’s absolute voltage limits and follow standard CMOS handling precautions to ensure reliable operation.
Features:
- Diode protection on all inputs.
- Single-supply operation.
- Supply voltage range: 3.0 Vdc to 18 Vdc.
- NOR input pin adjacent to VSS pin to simplify use as an inverter.
- NAND input pin adjacent to VDD pin to simplify use as an inverter.
- NOR output pin adjacent to inverter input pin for OR application.
- NAND output pin adjacent to inverter input pin for AND application.
- Capable of driving two low-power TTL loads or one low-power Schottky TTL load over the rated temperature range.
