74LVT16652ADL,512

Overview

The 74LVT16652ADL,512 is a high-performance BiCMOS product designed for VCC operation at 3.3 V. It functions as two 8-bit transceivers or one 16-bit bus interface register with 3-state outputs. The device features complimentary output enable inputs and select control inputs to choose between real-time transfer or stored data modes. It includes bus-hold data inputs to eliminate external pull-up resistors and supports live insertion and extraction. The component operates within an ambient temperature range of -40 °C to +85 °C.

Feature Summary

• Configurable as dual 8-bit or single 16-bit bus transceiver/register
• Select control inputs allow switching between real-time and stored data modes
• Bus-hold data inputs maintain unused input states without external components
• Supports live insertion and extraction with power-up 3-state functionality

Applications

• High-speed bus interface applications requiring data storage capabilities
• Systems utilizing 3.3 V logic levels with 5 V I/O interface requirements
• Bus management circuits needing simultaneous real-time and stored data handling

Procurement Notes

Verify the specific ordering suffix '512' corresponds to the SSOP56 package (SOT371-1) as documented in the official Nexperia datasheet. Confirm that the manufacturer designation aligns with Nexperia, which succeeded the NXP Standard Product business. Ensure compatibility with the specified 3.3 V operating voltage and 56-pin configuration before procurement.

Selection Notes

Select this component when a 16-bit bidirectional bus interface with internal latching is required. It is suitable for designs needing 3-state outputs and TTL-compatible input levels. Consider its capability for live insertion and its bus-hold feature if minimizing external passive components is a priority. Verify that the SSOP56 package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the 74LVT series of low-voltage CMOS logic devices. It is manufactured by Nexperia, following the separation of the NXP Standard Product business. The device integrates both transceiver and register functionalities into a single 56-pin package, providing flexibility for complex bus architectures in computing and industrial environments.

Replacement Considerations

The 74LVT16652ADGG is a pin-compatible alternative housed in a TSSOP56 package.
