產品概述
TEXAS INSTRUMENTS SN74AVC1T45DCKR 邏輯芯片, 非反相收發器, SC-70-6
TheSN74AVC1T45DCKRis a single-bit dual-supply Bus Transceiver with configurable voltage translation and 3-state outputs. The SN74AVC1T45 is optimized to operate with VCCA/VCCB set at 1.4 to 3.6V. It is operational with VCCA/VCCB as low as 1.2V. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 to 3.6V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.2 to 3.6V. The SN74AVC1T45 is designed for asynchronous communication between two data buses. The logic levels of the direction-control (DIR) input activate either the B-port outputs or the A-port outputs. The device transmits data from the A bus to the B bus when the B-port outputs are activated and from the B bus to the A bus when the A-port outputs are activated. The input circuitry on both A and B ports always is active and must have a logic HIGH or LOW level applied to prevent excess ICC and ICCZ. The SN74AVC1T45 is designed so that the DIR input is powered by VCCA.
. VCC Isolation feature - if either VCC input is at GND, all outputs are in high-impedance state . DIR input circuit referenced to VCCA . Ioff supports partial power-down mode operation . Latch-up performance exceeds 100mA per JESD 78, class II . ±12mA Output drive at 3.3V .I/Os are 4.6V tolerant
