SN74LVC8T245 SCES584C – JUNE 2005 – REVISED DECEMBER 2022 SN74LVC8T245 8-Bit Dual-Supply Bus Transceiver With Configurable Voltage Translation and 3-State Outputs 1 Features Control inputs VIH/VIL levels are referenced to VCCA voltage VCC isolation feature – if either VCC input is at GND, all are in the high-impedance state Fully configurable dual-rail design allows each port to operate over the full 1.65-V to 5.5-V powersupply range Latch-up performance exceeds 100 mA per JESD 78, class II ESD protection exceeds JESD 22 – 4000-V Human-Body Model (A114-A) – 100-V Machine Model (A115-A) – 1000-V Charged-Device Model (C101) 2 Applications Personal electronic Industrial Enterprise Telecom 2 DIR 3 A1 22 OE 21 B1 To Seven Other Channels Logic Diagram (Positive Logic) 3 Description The SN74LVC8T245 is an eight bit non-inverting bus transceiver with configurable dual power supply rails that enables bidirectional voltage level translation. The SN74LVC8T245 is optimized to operate with VCCA and VCCB set at 1.65 V to 5.5 V. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.65 V to 5.5 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the 1.8-V, 2.5V, 3.3-V, and 5.5-V voltage nodes. The SN74LVC8T245 is designed for asynchronous communication between two data buses. The logic levels of the direction-control (DIR) i...
