SN74LVC8T245 8-Bit Dual-Supply Bus Transceiver

SN74LVC8T245 8-Bit Dual-Supply Bus Transceiver With Configurable Voltage Translation and 3-State Outputs 1 Features 3 Description 1 This 8-bit noninverting bus transceiver uses two • Control Inputs VIH/VIL Levels Are Referenced to separate configurable power-supply rails. The VCCA Voltage SN74LVC8T245 is optimized to operate with VCCA • VCC Isolation Feature – If Either VCC Input Is at and VCCB set at 1.65 V to 5.5 V. The A port is GND, All Are in the High-Impedance State designed to track VCCA. VCCA accepts any supply • Fully Configurable Dual-Rail Design Allows Each voltage from 1.65 V to 5.5 V. The B port is designed Port to Operate Over the Full 1.65-V to 5.5-V to track VCCB. VCCB accepts any supply voltage from Power-Supply Range 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the 1.8-V, • Latch-Up Performance Exceeds 100 mA Per 2.5-V, 3.3-V, and 5.5-V voltage nodes. JESD 78, Class II The SN74LVC8T245 is designed for asynchronous • ESD Protection Exceeds JESD 22 communication between two data buses. The logic – 4000-V Human-Body Model (A114-A) levels of the direction-control (DIR) input and the – 100-V Machine Model (A115-A) output-enable (OE) input activate either the B-port outputs or the A-port outputs or place both output – 1000-V Charged-Device Model (C101) ports into the high-impedance mode. The device transmits data from the A bus to the B bus when the 2 Applications B-port outputs are activated, and from the B bus to • Personal Electronic the A bus when the A-port outputs are activated. The • Industrial input circuitry on both A and B ports is always active and must have a logic HIGH or LOW level applied to • Enterprise prevent excess ICC and ICCZ. • Telecom The SN74LVC8T245 is designed so that the control pins (DIR and OE) are supplied by VCCA.
