Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

74LVTH125
Low Voltage Quad Buffer with 3-STATE Outputs
Features
General Description
■ Input and output interface capability to systems at
The LVTH125 contains four independent non-inverting
buffers with 3-STATE outputs.
■
■
■
■
■
■
■
5V VCC
Bushold data inputs eliminate the need for external
pull-up resistors to hold unused inputs
Live insertion/extraction permitted
Power Up/Down high impedance provides glitch-free
bus loading
Outputs source/sink –32mA/+64mA
Functionally compatible with the 74 series 125
Latch-up performance exceeds 500mA
ESD performance:
– Human-body model > 2000V
– Machine model > 200V
– Charged-device model > 1000V
These buffers are designed for low-voltage (3.3V) VCC
applications, but with the capability to provide a TTL
interface to a 5V environment. The LVTH125 is fabricated with an advanced BiCMOS technology to achieve
high speed operation similar to 5V ABT while maintaining a low power dissipation.

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

Notes:
2. All typical values are at VCC = 3.3V, TA = 25°C.
3. An external driver must source at least the specified current to switch from LOW-to-HIGH.
4. An external driver must sink at least the specified current to switch from HIGH-to-LOW.
5. This is the increase in supply current for each input that is at the specified voltage level rather than VCC or GND.
