SN74LVC8T245-Q1
www.ti.com SCES815 – SEPTEMBER 2010 8-BIT DUAL-SUPPLY BUS TRANSCEIVER
WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3-STATE OUTPUTS
Check for Samples: SN74LVC8T245-Q1 FEATURES DESCRIPTION This 8-bit non-inverting bus transceiver uses two
separate configurable power-supply rails. The
SN74LVC8T245-Q1 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,
2.5-V, 3.3-V, and 5.5-V voltage nodes. 1 Qualified for Automotive Applications
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 Power-Supply Range
