Overview
The Nexperia 74HCT08DB,112 is a quad 2-input AND gate from the 74HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range of -40 °C to +125 °C. The device features TTL input levels and includes clamp diodes on all inputs. It provides four independent AND gates in a 14-lead SSOP package (SOT337-1). Static characteristics specify low leakage current and defined output voltage levels under standard load conditions.
Feature Summary
- Contains four independent 2-input AND logic gates
- TTL-compatible input voltage levels for direct interfacing with TTL systems
- Input clamp diodes allow use of current limiting resistors for voltages exceeding VCC
- High noise immunity and robust latch-up performance
Applications
- Digital logic circuits requiring multiple AND operations
- Signal gating and enable control in digital systems
- Interface between TTL and CMOS logic domains
Procurement Notes
Verify component authenticity through authorized distributors or official Nexperia channels. Confirm the specific ordering suffix matches the required package variant. Check for recent Product Change Notifications regarding manufacturing site transfers or marking updates. Ensure compliance with RoHS directives relevant to your region before procurement.
Selection Notes
Select this component when TTL-level compatibility is required alongside CMOS power efficiency. The 74HCT series bridges the gap between older TTL standards and modern CMOS technology. Verify that the operating voltage remains within the specified 4.5 V to 5.5 V range to ensure correct logic threshold behavior and propagation delay specifications.
Part Context
This part belongs to the widely used 74HCT logic family, designed for high-speed CMOS applications compatible with TTL inputs. The 'DB' suffix indicates the SSOP plastic small outline package variant. It serves as a fundamental building block for combinational logic design in industrial and consumer electronics.
