TC7LX1101WBG
1. Functional Description
•
Low-Voltage, Low-Power 1-Bit Dual-Supply Bus Transceiver with Auto Direction Sensing
2. General
The TC7LX1101WBG is an advanced high-speed dual-supply 1-bit bus transceiver fabricated with silicon-gate
CMOS technology.
The TC7LX1101WBG is designed for use as an interface between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-
V voltage systems.

control input. When the Output Enable (OE) input is low, the device is disabled, effectively isolating the buses.
All inputs and outputs of the TC7LX1101WBG can tolerate overvoltage conditions up to 3.6 V.
3. Features
(1) Voltage translation between arbitrary voltage levels from 1.2 V to 3.6 V.
(2) High-speed operation: tpd = 5.1 ns (max) (VCCA = 1.8 ± 0.15 V, VCCB = 3.3 ± 0.3 V)
(3) Latch-up performance: ±300 mA
(4) ESD performance:
Machine model ≥ ±200 V, Human body model ≥ ±2000 V
(5) Ultra-small package: WCSP6B
(6) The A-bus and B-bus are allowed to float. (when OE = Low)
(7) 3.6-V tolerant function and power-down protection provided on all inputs and outputs.
(8) All output ports are disabled when either VCC is switched off (VCCA/B=0V)
