SN74LVCH245APWRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCH245APWRG4 is an octal bus transceiver from the Texas Instruments LVCH logic series, housed in a TSSOP-20 package. It features three-state outputs and operates within a supply voltage range of 2 V to 3.6 V. The device supports TTL or CMOS input levels and provides LVTTL output levels. Key electrical parameters include a propagation delay of 7 ns, with low-level and high-level output currents rated at 24 mA and -24 mA respectively. It functions as a non-inverting bidirectional transceiver suitable for applications requiring direction control.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal bus transceiver architecture providing eight bidirectional data channels
• Three-state outputs allowing direct connection to bus lines
• Compatible with TTL and CMOS input logic levels

Buffers, Drivers, Receivers, Transceivers Applications

• Memory mapping controllers
• Clock drivers
• Bus-oriented communications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-20 package and 'G4' indicates lead-free/RoHS compliance per Texas Instruments documentation. Confirm the operating temperature range matches system requirements, typically -40°C to +85°C for this variant. Ensure ESD protection measures are adequate during handling due to moisture sensitivity classification.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal wide bus interface is required between devices operating at 3.3 V logic levels. The LVCH series offers lower power consumption compared to standard LVC variants while maintaining similar performance. Verify that the 24 mA drive current meets the load requirements of the connected bus lines and that the 7 ns propagation delay satisfies the timing constraints of the application.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVCH245A family of octal bus transceivers. It shares functional similarities with other members like the SN74LVCH245ARGYRG4 but differs in packaging, utilizing the TSSOP-20 form factor instead of VQFN. It serves as a standard solution for general-purpose bidirectional data transfer in digital systems.
