16-BIT DUAL-SUPPLY BUS TRANSCEIVER
WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3-STATE OUTPUTS
FEATURES
1
• 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 Outputs Are in the High-Impedance
State
• Overvoltage-Tolerant Inputs/Outputs Allow
Mixed-Voltage-Mode Data Communications
• Fully Configurable Dual-Rail Design Allows
Each Port to Operate Over the Full 1.65-V to
5.5-V Power-Supply Range
• Bus Hold on Data Inputs Eliminates the Need
for External Pullup/Pulldown Resistors
• I_off Supports Partial-Power-Down Mode
Operation
• Latch-Up Performance Exceeds 100 mA Per
JESD 78, Class II
• ESD Protection Exceeds JESD 22
– 2000-V Human-Body Model (A114-A)

DESCRIPTION/ORDERING INFORMATION
This 16-bit noninverting bus transceiver uses two separate configurable power-supply rails. The A port is
designed to track V_CCA. V_CCA accepts any supply voltage from 1.65 V to 5.5 V. The B port is designed to track
V_CCB. V_CCB 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-V voltage nodes.
The SN74LVCH16T245 is designed so that the control pins (1DIR, 2DIR, 1OE, and 2OE) are supplied by V_CCA.
