DIODES Incorporated Logic - Logic - Translators, Level Shifters - 74AVCH1T45DW-7 74AVCH1T45DW-7

The 74AVCH1T45DW-7 is a single-bit, dual-supply transceiver designed for voltage level translation between different logic levels ranging from 1.2V to 3.6V. It features 3-state outputs and includes a bus hold function that maintains the previous logic level at the inputs, eliminating the need for additional resistors for unused inputs. The device allows for direction control via a dedicated DIR pin, enabling the A pin to act as an input or output based on the logic level applied to DIR. This transceiver supports partial-power-down mode, ensuring high impedance output when either power supply is turned off, which prevents backflow currents and provides electrical isolation. The device is rated for an output drive of ±12mA at 3.3V and has high noise immunity with a typical hysteresis of 100mV. It is packaged in a SOT363 form factor and is fully compliant with RoHS standards, making it suitable for a variety of applications including mobile devices, computers, and networking equipment.
