74LVCH1T45GW,125

The 74LVCH1T45GW,125 from Nexperia is a single-bit, dual-supply translating transceiver designed for bidirectional level translation. It features two 1-bit input-output ports (A and B), a direction control input (DIR), and dual supply pins (VCC(A) and VCC(B)). Both VCC(A) and VCC(B) can be supplied at any voltage between 1.2 V and 5.5 V, making the device suitable for translating between various low-voltage nodes including 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V.

This transceiver offers a maximum data rate of 420 Mbps for 3.3 V to 5.0 V translation and operates within a temperature range of -40°C to +125°C. It includes IOFF circuitry for partial power-down applications and suspend mode functionality. The device is available in a 6-TSSOP package, suitable for surface mounting.

Key electrical characteristics include a wide supply voltage range of 1.2 V to 5.5 V, high noise immunity, and an output drive of ±24 mA at 3.0 V. The inputs can accept voltages up to 5.5 V, and it consumes a low quiescent current of 16 μA maximum. ESD protection is robust, exceeding 4000 V for HBM and 1000 V for CDM.
