SN74LXC8T245DGSR

The SN74LXC8T245 is an 8-bit, dual-supply noninverting bidirectional voltage level translation device. Ax pins and control pins (DIR and OE) are referenced to VCCA logic levels, and Bx pins are referenced to VCCB logic levels. The A port is able to accept I/O voltages ranging from 1.1V to 5.5V while the B port can accept I/O voltages from 1.1V to 5.5V. A high on DIR allows data transmission from A to B and a low on DIR allows data transmission from B to A when OE is set to low. When OE is set to high, both Ax and Bx pins are in the high-impedance state.

Applications

• Eliminate slow or noisy input signals
• Driving indicator LEDs or buzzers
• Debouncing a mechanical switch
• General purpose I/O level shifting
• Push-pull level shifting (UART, SPI, JTAG, and so forth)

Key features

• Fully configurable dual-rail design allows each port to operate from 1.1V to 5.5V
• Robust, glitch-free power supply sequencing
• Up to 420-Mbps support for 3.3V to 5.0V
• Schmitt-trigger inputs allow for slow or noisy inputs
• I/Os with integrated dynamic pull-down resistors help reduce external component count
• Control inputs with integrated static pull-down resistors allow for floating control inputs
• High drive strength (up to 32mA at 5V)
• Low power consumption: 4-μA maximum (25℃), 12-μA maximum (-40℃ to 125℃)
• VCC isolation and VCC disconnect (Ioff.flat) feature
• If either VCC supply is < 100mV or disconnected, all I/Os get pulled-down and then become high-impedance
• Ioff supports partial-power-down mode operation
• Compatible with LVC family level shifters
• Control logic (DIR and OE) are referenced to VCCA
• Operating temperature from -40℃ to +125℃
• Latch-up performance exceeds 100mA per JESD 78, Class II
• ESD protection exceeds JESD 22: 4000-V Human-Body Model, 1000-V Charged-Device Model
