74AC373MTCX

Latches Overview

The onsemi 74AC373MTCX is an octal transparent D-type latch featuring three-state outputs, housed in a 20-lead Thin Shrink Small Outline Package (TSSOP). Designed for bus-oriented systems, it provides eight independent latches within a single integrated circuit. The device operates with a supply voltage range of 2.0V to 6.0V and supports an operating temperature from -40°C to +85°C. It includes dedicated Latch Enable and Output Enable inputs to control data transparency and high-impedance states.

Latches Feature Summary

• Contains eight D-type latches with three-state outputs suitable for bus interfacing
• Outputs are capable of sourcing and sinking 24 mA current
• Latch Enable input controls data transparency while Output Enable manages high impedance

Latches Applications

• Bus organized system applications
• Data storage and buffering
• Interface between logic circuits and buses

Latches Procurement Notes

Verify the specific manufacturer origin as datasheets may reference Fairchild Semiconductor or onsemi due to corporate history. Confirm the TSSOP package dimensions match the MTC20 specification. Ensure the ordering suffix 'X' corresponds to tape and reel packaging requirements for your assembly process.

Latches Selection Notes

Select this component when an octal latch with three-state capability is required for bus architectures. Consider the 74ACT373 variant if TTL-compatible inputs are necessary, as the AC series does not inherently provide this feature. Verify that the 24 mA output drive strength meets the load requirements of the connected circuitry.

Latches Part Context

This part belongs to the 74AC logic family, which offers higher speed and lower power consumption compared to standard 74LS devices. The 74AC373 is functionally similar to the 74ACT373 but differs in input threshold characteristics. The MTCX suffix indicates the device is supplied in a tape and reel format for automated surface-mount assembly.

Latches FAQ

What is the difference between the 74AC373 and 74ACT373?

The primary difference lies in the input thresholds; the 74ACT373 features TTL-compatible inputs, whereas the 74AC373 uses CMOS thresholds.

How does the Output Enable pin function?

When the Output Enable (OE) input is LOW, the outputs are active. When OE is HIGH, the outputs enter a high-impedance state, isolating them from the bus.
