Common application and features of buffers, drivers, and transceivers

Reduce the impact of noise

Our high-speed complementary metal-oxide semiconductor with Schmitt-trigger (HCS) family performs over a wide 2- to 6-V input voltage range. Schmitt-trigger inputs help decipher clean signals in 3.3- and 5-V applications with high noise, and increase slow signal performance by sharpening logic-level transitions.

Application note
Reduce Noise and Save Power with the New HCS Logic Family (Rev. A)
Designers are continuously striving to improve signal integrity, reduce power, and increase robustness in their systems. TI's next-generation Schmitt-trigger Integrated High-speed CMOS family was designed to achieve these goals.

Application brief
Understanding Schmitt Triggers (Rev. A)
Most CMOS, BiCMOS and TTL devices require fast
edges on the high and low transitions of their inputs.
If the edges are too slow, they can cause excessive
current, oscillation, or may damage the device.

Generate a reset signal at system power on

Some systems require an initialization pulse. This is commonly generated by the system controller, however many systems need the initialization prior to the controller's startup, or they may not have a controller at all. In these cases, a simple circuit can provide the required pulse with no programming required.

Learn more about common applications of buffers

System controllers may have weak output drive strength, and may not be able to transmit over high capacitance lines. A buffer can be added inbetween the controller and the receiver to fix this issue.

Optimize board size with cost-efficient solutions


The SOT-23-Thin (DYY) package is the industry's smallest discrete logic leaded package measuring at 4.2 mm by 3.26 mm, which is 57% smaller than the TSSOP equivalent. With a standard 0.5 mm pitch, the DYY package easily integrates into the existing manufacturing equipment. The BQA package is TI's smallest 14-pin logic quad flat no-lead (QFN) package measuring at 3.0 mm by 2.5 mm, which is 76% smaller than the thin-shrink small-outline package (TSSOP) equivalent and 40% smaller than the previous-generation QFN package. This package also comes in wettable flank configurations to enable optical inspection as opposed to traditional X-ray inspection during manufacturing.

Redrive Digital Signals
System controllers can have weak output drive strength and thus cannot be used to directly transmit over relatively high capacitance signal lines. A logic buffer can be added to reduce loading and improve signal integrity.
