SN74LXC1T14
- Fully configurable dual-rail design allows each port to operate from 1.1 V to 5.5 V
- Robust, glitch-free power supply sequencing
- Up to 420-Mbps support for 3.3 V to 5.0 V
- Schmitt-trigger inputs allow for slow or noisy inputs
- Input with integrated dynamic pull-down resistors help reduce external component count
- High drive strength (up to 32 mA at 5 V)
- Low power consumption
- 3-µA maximum (25°C)
- 6-µA maximum (–40°C to 125°C)
- VCC isolation and Vcc disconnect (Ioff-float) feature
- If either VCC supply is < 100 mV or disconnected, all I/Os get pulled-down and then become high-impedance
- Overvoltage tolerant inputs accept voltages up to 5.5 V regardless of supply voltage.
- Ioff supports partial-power-down mode operation
- Operating temperature from –40°C to +125°C
- Latch-up performance exceeds 100 mA per JESD 78, class II
- ESD protection exceeds JESD 22
- 4000-V human-body model
- 1000-V charged-device model
The SN74LXC1T14 is a single bit, dual-supply inverting voltage level translation device with Schmitt-trigger input. The input pin A is referenced to VCCI logic levels, and output pin Y is referenced to VCCO logic levels. The input pin A is able to accept voltages ranging from 1.1 V to 5.5 V and can be connected directly to VCCI or GND. See Device Functional Modes for a summary of the operation of the logic.
This device ensures low power consumption and is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs when the device is powered down. This inhibits current backflow into the device which prevents damage to the device.
