Texas Instruments TXU0304/TXU0304-Q1 Unidirectional Level Shifter

Texas Instruments TXU0304/TXU0304-Q1 4-Bit Unidirectional Level Shifter is a dual-supply noninverting fixed direction voltage level translation device. Ax pins are referenced to the V_CCA logic level, OE pin can be referenced to either V_CCA or V_CCB logic levels, and Bx pins are referenced to V_CCB logic levels. The A port can accept input voltages ranging from 1.1V to 5.5V, while the B port can also accept input voltages from 1.1V to 5.5V. Fixed direction data transmission can occur from A to B or B to A when OE is set too high in reference to either supply. When the Texas Instruments TXU0304/TXU0304-Q1 OE is set to low, all output pins are in the high-impedance state.

Features

AEC-Q100 qualified for automotive applications
A fully configurable dual-rail design allows each port to operate from 1.1V to 5.5V
Up to 200Mbps support for 3.3V to 5.0V
Schmitt-trigger inputs allow for slow and noisy inputs
Inputs with integrated static pull-down resistors prevent channels from floating
High drive strength (up to 12mA at 5V)
Low power consumption
- 3µA maximum (25°C)
- 6µA maximum (–40°C to 125°C)
V_CC isolation and V_CC disconnect (I_off-float) feature
- If either V_CC input is < 100mV or disconnected, all outputs are disabled and become high-impedance

I_off supports partial-power-down mode operation
Control logic (OE) with V_CC(MIN) circuitry allows for control from either A or B port
Pinout compatible with TXB family level shifters
Available in other variants that support common applications (TXU0104-Q1, TXU0204-Q1)
Operating temperature from –40°C to +125°C
Latch-up performance exceeds 100mA per JESD 78, class II
ESD protection exceeds JESD 22
- 2500V human-body model
- 1500V charged-device model
