SN74BCT373DWG4

Overview

The SN74BCT373DWG4 is an octal transparent D-type latch with 3-state outputs manufactured by Texas Instruments. It utilizes state-of-the-art BiCMOS design to significantly reduce quiescent current. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating free-air temperature range of 0°C to 70°C. It features eight latches that are transparent while the latch-enable input is high, latching data when the enable goes low. The outputs can be placed in a high-impedance state via a buffered output-enable input.

Feature Summary

• State-of-the-art BiCMOS design reduces ICCZ
• Transparent D-type latches for parallel access loading
• 3-state outputs suitable for bus lines or memory address registers
• ESD protection exceeds JESD 22 specifications

Applications

• Buffer registers
• I/O ports
• Bidirectional bus drivers
• Working registers

Procurement Notes

Verify the specific ordering suffix 'DWG4' against the manufacturer's official documentation to confirm package type, lead finish, and environmental compliance status. Ensure the component meets the required RoHS standards and moisture sensitivity level ratings for your assembly process. Cross-reference the part number with the latest Package Option Addendum to validate availability and production status before finalizing procurement.

Selection Notes

Select this component for applications requiring octal data storage with high-impedance bus driving capabilities. The BiCMOS technology offers lower power consumption compared to standard CMOS alternatives. Ensure the system operates within the specified 4.5 V to 5.5 V supply voltage range and the 0°C to 70°C temperature limits. Verify that the propagation delay characteristics meet the timing requirements of the target digital interface.

Part Context

This device belongs to the SN74BCT373 family of octal transparent D-type latches with 3-state outputs. It is designed specifically for driving highly capacitive or relatively low-impedance loads. The 'DW' designation indicates a SOIC package, while the 'G4' suffix typically denotes lead-free and RoHS-compliant manufacturing. It serves as a key component in digital logic circuits requiring parallel data buffering and bus isolation.
