Manufacturer Part Number

SN74LVC16245AGQLR

Description

High-speed, low-voltage (1.65V to 3.6V) octal bidirectional transceiver IC. Non-inverting logic signal transmission. Supports 2 independent 8-bit channels, total 16 bits. Features three-state outputs for bus applications. 56-BGA Microstar Junior package for small footprint and surface mount. Useful for high-density PCB layouts. Obsolete status, not recommended for new designs.

Specifications

2 elements, each 8 bits wide (16 bits total). Output type 3-state allows multiple connections to a common bus. Output current ±24mA, supports driving moderate loads. Supply voltage from 1.65V to 3.6V. Supports operation across -40°C to 85°C temperature range. Low power CMOS technology. RoHS3 Compliant, REACH unaffected, MSL1 (unlimited shelf life). ECCN EAR99, HTSUS 8542.39.0001.

Device Structure

Solid-state CMOS transceiver. Integrated 2 x 8-bit non-inverting tri-state output channels. Packaged in 56-ball fine-pitch BGA (Microstar Junior 7x4.5mm). Designed for surface mount assembly. Small size supports compact designs.

Performance Characteristics

High output drive of 24mA both high and low. Fast propagation delay for high-speed data transfer. Wide input and output voltage acceptance within supply range. Low static power consumption. High noise immunity due to CMOS technology.

Application Environments

Used in digital systems needing bidirectional data pathways, such as data busses, peripheral interfaces, or memory controllers. Well suited for battery-powered or low-voltage systems. Common in computing, telecom, industrial, and embedded designs. Not suitable for new designs (obsolescence).

Selection Guidelines

Only select if exact replacement for an existing SN74LVC16245AGQLR is required. For new designs, consider current production alternatives. Check supply voltage and output current fit your requirements. Ensure BGA package compatible with assembly process. Confirm RoHS and REACH if needed for compliance.

Usage Considerations

Sensitive to standard ESD and handling precautions. Reflow soldering required for BGA mounting. Ensure all pins correctly connected for intended data direction. Review obsolescence risk for long-term supply. Avoid for designs needing extended life-cycle support.

Potential Equivalent/Replacement Models

This model is obsolete. Texas Instruments 74LVC16245 family offers similar parts in different packages, like TSSOP (e.g., SN74LVC16245ADGVR, SN74LVC16245AZQLR), which may still be available. Other manufacturers such as Nexperia (74LVC16245ADB) or ON Semiconductor/Diodes Incorporated may offer equivalents.
