SN74AVC8T245
8-BIT DUAL-SUPPLY BUS TRANSCEIVER
WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3-STATE OUTPUTS
SCES517H – DECEMBER 2003 – REVISED FEBRUARY 2007
FEATURES
• Control Inputs V_IH/V_IL Levels Are Referenced
to V_CCA Voltage
• V_CC Isolation Feature – If Either V_CC Input Is at
GND, All I/O Ports Are in the High-Impedance
State
• I_off Supports Partial Power-Down-Mode
Operation
• Fully Configurable Dual-Rail Design Allows
Each Port to Operate Over the Full 1.4-V to
3.6-V Power-Supply Range
• I/Os Are 4.6-V Tolerant
• Max Data Rates
– 170 Mbps (V_CCA < 1.8 V or V_CCB < 1.8 V)
– 320 Mbps (V_CCA ≥ 1.8 V and V_CCB ≥ 1.8 V)
• Latch-Up Performance Exceeds 100 mA Per
JESD 78, Class II
• ESD Protection Exceeds JESD 22
– 8000-V Human-Body Model (A114-A)
– 200-V Machine Model (A115-A)
– 1000-V Charged-Device Model (C101)

DESCRIPTION/ORDERING INFORMATION
This 8-bit noninverting bus transceiver uses two separate configurable power-supply rails. The SN74AVC8T245
is optimized to operate with V_CCA/V_CCB set at 1.4 V to 3.6 V. It is operational with V_CCA/V_CCB as low as 1.2 V. The
A port is designed to track V_CCA. V_CCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to
track V_CCB. V_CCB accepts any supply voltage from 1.2 V to 3.6 V. This allows for universal low-voltage
bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.
