The SN74AVC1T45DCKR from Texas Instruments is a single-bit dual-supply bus transceiver used for voltage level translation between two logic rails. Each of its two supply pins accepts 1.2 V to 3.6 V, so the SN74AVC1T45DCKR can translate in either direction between any pair of levels in that range under direction-pin control. It is supplied in a 6-pin SC-70 package on tape and reel and is rated for -40 C to 85 C operation.

Voltage level shifters like the SN74AVC1T45DCKR sit between subsystems that run on different logic supplies, such as a 1.8 V processor core talking to a 3.3 V sensor, memory or peripheral. Its 1.2 V to 3.6 V dual-rail range and 500 Mbps data rate suit SPI, I2C-style control lines and general single-bit interface signals in portable, industrial and consumer designs. Hardware engineers and contract manufacturers building mixed-voltage boards specify this part where a single translated signal is needed in a very small footprint. The -40 C to 85 C rating covers commercial and light industrial environments.
