74LVC16245APAG

Overview

The Renesas 74LVC16245APAG is a 16-bit non-inverting bus transceiver designed for operation within a supply voltage range of 3.0 V to 3.6 V. It features two output enables and two direction control inputs, allowing configuration as a single 16-bit or dual 8-bit transceiver. The device provides three-state outputs with low-level output currents up to 24 mA and high-level output currents up to -24 mA. It supports LVTTL input and output levels, ensuring compatibility with standard logic families. The propagation delay is specified at 4.7 ns under maximum capacitive load conditions. Operating temperatures range from -40 °C to +85 °C, housed in a 48-pin TSSOP package.

Feature Summary

• Dual-directional data flow control via separate DIR inputs for each octet
• Partial power-down protection through I_OFF circuitry to prevent backflow current
• Schmitt-trigger inputs provide noise immunity against slow rise and fall times
• Compatible with mixed 3.3 V and 5 V environments due to overvoltage tolerant inputs

Applications

• Memory mapping in embedded systems
• Clock drivers and buffered oscillators
• Bus-oriented communications

Procurement Notes

Verify the specific suffix APAG confirms the TSSOP-48 package and industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status with the manufacturer prior to ordering. Check for obsolescence notices as legacy logic components may face end-of-life transitions. Ensure design-in documentation matches the exact pinout and electrical characteristics defined in the official datasheet.

Selection Notes

Select this component when interfacing between 3.3 V logic domains requiring bidirectional data transfer. The 16-bit width reduces board space compared to multiple 8-bit devices. Verify that the system voltage remains within the 3.0 V to 3.6 V operational window. Consider the 4.7 ns propagation delay for timing constraints. Ensure thermal management supports the specified operating temperature range for industrial applications.

Part Context

This part belongs to the Renesas 74LVC family of CMOS logic devices, derived from IDT technology acquired by Renesas. It serves as a standard interface solution for high-density digital systems. The LVC series offers lower power consumption compared to older LVX or HCT families while maintaining fast switching speeds suitable for modern embedded controllers and communication interfaces.

Replacement Considerations

Nexperia 74LVC16245ADGG: Pin-compatible alternative with similar electrical specifications and wider voltage tolerance. Texas Instruments SN74LVC16245ADGGR: Functionally equivalent 16-bit transceiver in TSSOP-48 packaging. Verify pin assignments and electrical limits before substitution.
