Overview
The onsemi 74ACT02MTC is a quad 2-input NOR gate in the 74ACT logic family, housed in a 14-lead Thin Shrink Small Outline Package (TSSOP). It operates within a supply voltage range of 4.5V to 5.5V and supports an ambient operating temperature from -40°C to +85°C. The device features TTL-compatible inputs and outputs capable of sourcing or sinking 24mA. Propagation delays are specified at a maximum of 9.0ns for high-to-low transitions and 9.5ns for low-to-high transitions at 5.0V.
Feature Summary
- Contains four independent 2-input NOR gates
- Features TTL-compatible input thresholds
- Provides robust output drive capability with 24mA source/sink current
Applications
- Digital logic signal processing
- General-purpose combinational logic circuits
- Microprocessor system interface gating
Procurement Notes
Verify the specific ordering suffix 'MTC' confirms the TSSOP package variant. Confirm RoHS compliance status through official manufacturer documentation. Ensure the component matches the original Fairchild Semiconductor specifications now managed by onsemi. Check for any recent product change notices affecting pinout or electrical characteristics.
Selection Notes
Select this component when TTL-level compatibility is required alongside CMOS noise immunity. The TSSOP package is suitable for space-constrained surface-mount designs. Consider the ACT series for faster switching speeds compared to standard HC logic families while maintaining 5V operation.
Part Context
This part belongs to the 74AC/ACT logic family, originally developed by Fairchild Semiconductor and now distributed by onsemi. The 74ACT series bridges the gap between AC speed and ACT input compatibility. The MTC suffix specifically denotes the 14-lead TSSOP physical footprint.
Replacement Considerations
Equivalent parts include MC74ACT02DR2G and MM74HC02MTC, though logic families differ. Verify pinout compatibility before substitution. Cross-reference datasheets for exact propagation delay and power consumption differences.
