74ABT16500CMTDX

Overview

The onsemi 74ABT16500CMTDX is an 18-bit universal bus transceiver housed in a 56-lead Thin Shrink Small Outline Package (TSSOP). It integrates D-type latches and flip-flops to support transparent, latched, and clocked data modes. The device operates within a supply voltage range of +4.5V to +5.5V and supports an ambient temperature range of -40°C to +85°C. Key electrical parameters include a maximum propagation delay of 5.3 ns and a maximum clock frequency of 150 MHz under standard conditions.

Feature Summary

• Combines D-type latches and flip-flops for flexible data flow control
• Provides glitch-free high impedance during power-up and power-down cycles
• Supports non-destructive hot insertion capabilities

Applications

• Universal bus transceivers requiring registered data storage
• High-speed data routing systems with latch/flip-flop functionality
• Bus architectures utilizing complementary output enable signals

Procurement Notes

Verify the specific package designation MTD56 corresponds to the 56-lead TSSOP configuration. Confirm that the ordering suffix matches the required tape and reel format if applicable. Ensure compliance with the manufacturer's life support policy restrictions before deployment in critical systems.

Selection Notes

Select this component when an 18-bit width is required alongside integrated registration capabilities. The ABT series offers high-speed performance suitable for demanding bus applications. Verify that the system design accommodates the complementary nature of the OEAB and OEBA control signals.

Part Context

This device belongs to the ABT logic family, which utilizes BiCMOS technology for high-speed operation. The 74ABT16500 variant specifically addresses applications needing both bus driving and data storage functions within a single integrated circuit package.

Replacement Considerations

Consult official cross-reference documentation for verified substitutes. Ensure any replacement maintains the 18-bit width, TSSOP-56 package, and compatible ABT series electrical characteristics.
