1. Functional Description
•
Low-Voltage, Low-Power 1-Bit Dual-Supply Bus Buffer
2. General
The TC7SPN334L6X is a CMOS high-speed single-bit bus buffer designed to interface between two subsystems
operating at different voltage levels between 1.1 V and 3.6 V.
Its input and output provide overvoltage tolerance and accept up to 3.6 V in power-down mode (power-down
protection).
The TC7SPN334L6X dual-supply bus buffer operates with a VCCA of 1.2 V, 1.5 V, 1.8 V, or 2.5 V bus and a VCCB
of 1.8 V, 2.5 V or 3.3 V. It is suitable for single-bit interfacing.
The A input interfaces with the 1.2 V, 1.5 V, 1.8 V or 2.5 V bus, and the B output interfaces with the 1.8 V, 2.5 V,
3.3 V bus.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
3. Features

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: Don't supply a voltage to VCCB pin when VCCA is in the OFF state.
Note 2: High (H) or Low (L) state. IOUT absolute maximum rating must be observed.
Note 3: VOUT < GND, VOUT > VCC

Note:
The operating ranges must be maintained to ensure the normal operation of the device.
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.
Note 1: Output in OFF state.
Note 2: High (H) or Low (L) state.
