DESCRIPTION/ORDERING INFORMATION
SN74AVC8T245
8-BIT DUAL-SUPPLY BUS TRANSCEIVER
WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3-STATE OUTPUTS
SCES517H – DECEMBER 2003 – REVISED FEBRUARY 2007
• Control Inputs V
IH/VIL Levels Are Referenced
• Max Data Rates
to V
CCA Voltage
170 Mbps (V
CCA < 1.8 V or VCCB < 1.8 V)
• V
CC Isolation Feature – If Either VCC Input Is at
320 Mbps (V
CCA ≥ 1.8 V and VCCB ≥ 1.8 V)
GND, All I/O Ports Are in the High-Impedance
• Latch-Up Performance Exceeds 100 mA Per
State
JESD 78, Class II
• I
off Supports Partial Power-Down-Mode
• ESD Protection Exceeds JESD 22
Operation
8000-V Human-Body Model (A114-A)
• Fully Configurable Dual-Rail Design Allows
200-V Machine Model (A115-A)
Each Port to Operate Over the Full 1.4-V to
1000-V Charged-Device Model (C101)
3.6-V Power-Supply Range
• I/Os Are 4.6-V Tolerant
This 8-bit noninverting bus transceiver uses two separate configurable power-supply rails. The SN74AVC8T245
is optimized to operate with VCCA/VCCB set at 1.4 V to 3.6 V. It is operational with VCCA/VCCB as low as 1.2 V. The
A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to
track VCCB. VCCB 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.
