TC7W126FUTE12LF

Overview

The TC7W126FUTE12LF is a dual bus buffer utilizing C2MOS technology, providing non-inverting logic with three-state outputs. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature from -40°C to +85°C. The device features a typical propagation delay of 10 ns at 5 V and maintains a maximum quiescent current of 2 µA. Output drive capability supports up to 15 LSTTL loads, with symmetrical output impedance ensuring balanced signal transitions.

Feature Summary

• High-speed operation comparable to equivalent LSTTL standards while maintaining low power dissipation characteristics.
• Three-state control input allows outputs to enter high-impedance state when the enable signal is set low.
• Integrated protection circuits on all inputs safeguard against static discharge and transient excess voltage events.

Applications

• Bus-oriented memory and register applications requiring data buffering
• Clock drivers for distributing timing signals across digital systems
• Input/output buffering for consumer appliances and office automation equipment

Procurement Notes

Verify the specific ordering suffix matches the required package configuration before procurement. Confirm RoHS compliance status directly with the manufacturer or authorized distributor as environmental declarations may vary by production lot. Ensure the component meets the intended application's reliability requirements by consulting the Toshiba Semiconductor Reliability Handbook.

Selection Notes

Select this component for designs requiring wide voltage compatibility between 2 V and 6 V. The C2MOS process offers a balance of speed and power efficiency suitable for battery-operated devices. Verify that the SSOP-8 package dimensions align with the PCB footprint constraints and that the thermal dissipation capabilities are sufficient for the expected operating environment.

Part Context

This part belongs to the TC7W126 series of dual bus buffers manufactured by Toshiba Semiconductor and Storage. The 'FU' designation indicates the standard SSOP-8 package, while the 'TE12LF' suffix specifies the tape and reel packaging format with lead-free composition. This series is designed for general-purpose digital logic buffering in compact electronic assemblies.

FAQ

What is the function of the G input pin?

The G input serves as the three-state control. Setting it low places the outputs into a high-impedance state, effectively disconnecting them from the bus.

How does the TC7W126 handle noise immunity?

The device provides high noise immunity with minimum noise input voltages (VNIH and VNIL) defined as 28% of the supply voltage (VCC).
