74ALVCH162374T

Overview

The Fairchild Semiconductor 74ALVCH162374T is a 16-bit D-type flip-flop with 3-state outputs, designed for low-voltage applications. It operates within a supply voltage range of 1.65 V to 3.3 V and features a propagation delay of 9.6 ns. The device provides high-level output current capability of -12 mA and is housed in a TSSOP-48 surface-mount package. It supports single-ended inputs and non-inverting logic polarity, functioning across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides 16-bit data storage with 3-state output control for bus-oriented applications
• Supports low-voltage operation from 1.65 V to 3.3 V with TTL interface capability
• Features bushold data inputs to eliminate the need for external pull-up resistors on unused lines

Applications

• Bus oriented memory and data register applications
• Low-voltage microprocessor systems
• Portable and battery-powered electronic devices

Procurement Notes

Verify the specific suffix 'T' against official datasheets to confirm tape-and-reel packaging requirements. Confirm that the component meets RoHS compliance standards if required by your manufacturing process. Ensure the supplier provides valid traceability documentation for this obsolete or end-of-life part number. Cross-reference the manufacturer code to distinguish between original Fairchild and subsequent onsemi production runs.

Selection Notes

Select this component when designing systems requiring 16-bit parallel data latching with low power consumption. It is suitable for environments where 3.3 V or lower supply voltages are standard. Consider the bushold feature if the design involves unused input lines to simplify circuit layout. Verify that the TSSOP-48 package dimensions fit the available PCB space constraints.

Part Context

This device belongs to the ALVCH series of advanced low-voltage CMOS logic components. It is functionally similar to other 16-bit flip-flops but optimized for sub-3.3 V operation. The part integrates clock and output enable controls common to all bits, allowing byte-controlled or full-word operation depending on pin configuration.

Replacement Considerations

Check for direct substitutes like the 74VCXH162374MTX which shares similar specifications and packaging. Verify pin compatibility and electrical characteristics before swapping components.
