1. Functional Description
•
Low-Voltage, Low-Power 2-Bit Dual-Supply Bus Transceiver with Auto Direction Sensing
2. General
The TC7LX1102FK is an advanced high-speed dual-supply 2-bit bus transceiver fabricated with silicon-gate
CMOS technology.
The TC7LX1102FK 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.
The voltage translator automatically senses the direction of data transmission, eliminating the need for a direction
control input. When the Output Enable (OE) input is low, the device is disabled, effectively isolating the buses.
All inputs and outputs of the TC7LX1102FK 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 = 5.0 ns (max) (VCCA = 1.8 ± 0.15 V, VCCB = 3.3 ± 0.3 V)
(3)
Latch-up performance: ±300 mA
(4)
ESD performance:
(5)
Ultra-small package: US8
(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)
Machine model ≥ ±200 V, Human body model ≥ ±2000 V

7. Internal Equivalent Circuit
The TC7LX1102FK does not have a control signal that controls the direction of data flow between A and B. In a
DC state, the output circuit holds either High or Low level, but since it is designed to have a weak drive strength
(with a typical output resistance of 5.5 kΩ), an overdrive signal from the external driver can change the direction
of data flow.
The output one-shot circuits detect either a rising or falling edge on the A or B port. During the rise time, the
output one-shot circuit associated with the PMOS transistors turns it on for a certain period to speed up a
transition from Low to High. Likewise, during the fall time, the output one-shot circuit associated with the NMOS
transistors turns it on to speed up a transition from High to Low.

Note:
Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even
destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even
if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum
ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report
and estimated failure rate, etc).
Note 1: Output in OFF state.
Note 2: High or low state. IOUT absolute maximum rating must be observed.
Note 3: VOUT < GND, VOUT > VCC

Unused inputs and bus inputs must be tied to either VCC or GND. Please connect both bus inputs and the bus
outputs with VCC or GND when the I/O of the bus terminal changes by the function. In this case, please note
that the output is not short-circuited.
