SN74LXC8T245의 주요 특징
- 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
- 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 32 mA at 5 V)
- Low power consumption:
- 4-µA maximum (25°C)
- 12-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
- 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°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
SN74LXC8T245에 대한 설명
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 1.1 V to 5.5 V, while the B port can accept I/O voltages from 1.1 V to 5.5 V. 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. See Device Functional Modes for a summary of the operation of the control logic.
