Product details

Dual 8-bit bus transceiver for 3.3 V backplanes

Each of the two elements handles 8 bits with independent direction and output-enable controls. Output drive is rated at 12 mA source and 12 mA sink per channel, enough for standard CMOS inputs and short PCB traces; for longer backplane runs or higher fan-out, plan on buffering or using a higher-drive variant.

Tape & Reel and Cut Tape options are available for both production reels and prototype quantities.

Lifecycle and regulatory status

No last-time-buy window is open, and no successor has been announced. The part is fully qualified for ongoing production and new designs. ROHS3 compliant per current TI declarations, with no exemption conflicts for EU, UK, or other ROHS-regulated markets. No additional substance restrictions beyond ROHS3 are stated.

Frequently asked questions

What is the difference between SN74LVCR162245DGGR and SN74AVCH162245?

The SN74AVCH162245 is a higher-performance 16-bit transceiver from TI's 74AVCH series, typically offering wider supply range (1.65 V to 3.6 V) and lower propagation delay. The SN74LVCR162245DGGR is a 74LVCR-series part with a narrower 2.7 V to 3.6 V supply and moderate speed. If your bus runs at 3.3 V and you need lower power or wider voltage tolerance, the AVCH variant is worth evaluating; for a standard 3.3 V backplane, the LVCR part is cost-effective and fully adequate.

Does SN74LVCR162245DGGR support 5V inputs?

No — the supply voltage range is 2.7 V to 3.6 V, and the device is not specified for 5 V tolerant inputs. Applying 5 V to any I/O pin exceeds the absolute maximum ratings and risks damage. For 5 V-tolerant logic, look at TI's 74LVC or 74AVC families with 5 V-tolerant I/O.

Is SN74LVCR162245DGGR RoHS compliant?

Yes, the SN74LVCR162245DGGR is ROHS3 compliant per TI's current declaration, with no exemptions that restrict its use in EU or UK markets.

When sourcing SN74LVCR162245DGGR, what's the closest functional second-source — SN74LVTH16245ADGVR?

The SN74LVTH16245ADGVR is a 74LVTH-series 16-bit transceiver with higher output drive (32 mA vs 12 mA) and a 2.7 V supply minimum, but it is not a direct pin-for-pin second source. The pinout and footprint are similar (both 48-TSSOP), but the LVTH part's higher drive and different bus-hold characteristics may require re-evaluating termination and fan-out. For a true second source with identical specs, stick with the same 74LVCR series; the LVTH is a functional alternative only after timing and load analysis.
