74LVT16501ADL,512

Universal Bus Functions Overview

The 74LVT16501ADL,512 is a high-performance BiCMOS universal bus transceiver designed for VCC operation at 3.3 V. It features 18-bit bidirectional data paths with non-inverting 3-state outputs in both send and receive directions. Data flow is controlled by output enable (OEAB/OEBA), latch enable (LEAB/LEBA), and clock (CPAB/CPBA) inputs. The device supports transparent mode or positive-edge triggered latching depending on control states. It includes active bus hold circuitry to maintain valid logic levels on unused inputs.

Universal Bus Functions Feature Summary

• 18-bit bidirectional bus interface with 3-state buffers
• TTL input and output switching levels with 5 V system interface capability
• Active bus hold data inputs eliminate the need for external pull-up resistors
• Positive-edge triggered clock inputs with power-up reset and 3-state functionality

Universal Bus Functions Applications

• High-speed bi-directional data transfer between buses
• Memory mapping applications requiring 3-state isolation
• Clock distribution and buffering in 3.3 V systems

Universal Bus Functions Procurement Notes

Verify the specific ordering suffix 'DL,512' corresponds to the SSOP56 package (SOT371-1) and the -40 °C to +85 °C temperature range as defined in the manufacturer's ordering table. Confirm that the component source aligns with Nexperia standards, noting the historical transition from NXP Semiconductors branding for this product line.

Universal Bus Functions Selection Notes

Select this component for designs requiring an 18-bit wide data path operating at 3.3 V. Ensure the application utilizes TTL-compatible voltage levels and requires 5 V tolerant I/O interfaces. Verify that the SSOP56 package dimensions fit the PCB layout constraints and that the required propagation delays meet the system timing specifications under the target load conditions.

Universal Bus Functions Part Context

This device belongs to the LVT logic family, optimized for 3.3 V supply voltages. It serves as a universal transceiver, combining the functions of a buffer and a register. The ADL variant specifically denotes the shrink small outline plastic package with 56 leads, distinguishing it from other package options like TSSOP within the same functional series.
