74ACT16245DL

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ACT16245DL is a 16-bit bus transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features non-inverting logic with three-state outputs. The device utilizes an SSOP-48 package and supports a propagation delay of 8.4 ns. It functions as two independent 8-bit transceivers or one 16-bit transceiver, designed for TTL input levels and CMOS output levels across an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional data transmission via 16-bit configuration
• Features three-state outputs for effective bus line management
• Supports conversion between TTL input and CMOS output logic levels

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed data bus architectures requiring 16-bit width
• System memory interface circuits
• Control signal routing in industrial automation equipment

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific manufacturer designation on the component marking, as the '74' prefix may indicate an onsemi product while the 'SN' prefix indicates Texas Instruments. Confirm the package type matches the required SSOP-48 footprint. Ensure the design accommodates the specified 4.5 V to 5.5 V power supply constraints and check for end-of-life status if long-term availability is critical.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 5 V system requires a 16-bit wide bus interface with high drive capability. The TTL-compatible inputs allow direct interfacing with legacy logic families. Consider the propagation delay specifications against the system clock speed requirements. Verify that the thermal performance of the SSOP-48 package meets the application's heat dissipation needs.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACT logic family, which offers faster switching speeds compared to standard 74LS series devices while maintaining compatibility with 5 V CMOS systems. The 16245 designation specifically identifies it as a wide bus transceiver, distinguishing it from narrower 8-bit variants within the same logical architecture.
