MC74AC373N

Latches Overview

The MC74AC373N is an octal transparent latch with 3-state outputs manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40°C to +85°C. The device features eight D-type latches in a single package, providing non-inverting data paths. Propagation delays are specified at 9.5 ns maximum at 5.0 V and 13.5 ns maximum at 3.3 V. Quiescent supply current is limited to 80 µA maximum. Outputs can source or sink up to 24 mA. The component is housed in a 20-lead PDIP package.

Latches Feature Summary

• Contains eight D-type latches with 3-state standard outputs for bus interfacing
• Transparent operation when Latch Enable input is HIGH
• Outputs enter high impedance state when Output Enable input is HIGH

Latches Applications

• Bus organized system applications
• Data storage and buffering
• Bus interfacing

Latches Procurement Notes

Verify the specific ordering suffix to confirm the package type and shipping quantity. The 'N' suffix indicates a 20-lead PDIP package. Confirm RoHS compliance status as indicated in the ordering information section. Ensure the procurement channel provides valid traceability documentation for the component lot.

Latches Selection Notes

Select this component for designs requiring octal latching with tri-state control. Compare propagation delay specifications against system timing requirements at the target operating voltage. Verify that the output drive capability meets the load requirements of the connected circuitry. Consider the PDIP package constraints for PCB layout and thermal management.

Latches Part Context

This part belongs to the MC74AC373/74ACT373 family of octal transparent latches. The AC series offers higher speed performance compared to HC variants. The N suffix specifically denotes the through-hole PDIP package format. This family is designed for general-purpose digital logic applications requiring data storage and bus isolation.
