Overview
The onsemi 74LVX574MTC is an octal D-type flip-flop featuring positive-edge triggering and three-state outputs. It operates within a supply voltage range of 2V to 3.6V, with a maximum propagation delay of 18ns at 2.7V and 12.8ns at 3.3V. The device provides 4mA output drive current in both high and low states, draws 4µA static current, and functions across a temperature range of -40°C to +85°C. It is housed in a 20-TSSOP package.
Feature Summary
- Positive-edge triggered octal D-type flip-flop architecture
- Three-state non-inverting outputs for bus-oriented systems
- Low quiescent current operation for power efficiency
- Wide operating voltage range supporting 2V to 3.6V systems
Applications
- Bus-oriented memory register implementations
- I/O port buffering and data storage
- Clock domain crossing synchronization circuits
- Parallel-to-serial data conversion interfaces
Procurement Notes
Verify the specific suffix 'MTC' confirms the 20-TSSOP surface-mount package configuration. Confirm RoHS compliance status through official manufacturer documentation. Check for obsolescence notices or last-time-buy dates directly from onsemi channels. Ensure pinout compatibility matches the target PCB footprint design requirements before finalizing procurement decisions.
Selection Notes
Select this component when low-voltage operation between 2V and 3.6V is required. Choose the LVX series for faster switching speeds compared to standard HC logic families. Consider the TSSOP-20 package for compact surface-mount assembly needs. Evaluate the 4mA drive capability against load requirements to ensure signal integrity without additional buffering stages.
Part Context
This part belongs to the 74LVX family of low-voltage CMOS logic devices. It serves as an octal edge-triggered storage element within digital circuit designs. The device complements other LVX components like latches and buffers. It supports modern low-power applications requiring reliable data retention and fast transition times.
