QS3VH253QG8

QS3VH253QG8 is a digital-logic integrated circuit, typically part of the VH (Very High Speed CMOS) family. It functions as an 8-bit latch/buffer with tri-state outputs, used to store and buffer data on a digital bus and to enable safe sharing of lines among multiple devices. Key features usually include a latch/store enable input to capture data and an output-enable input to place the outputs in a high-impedance state when not driving a bus. It is designed for fast operation in compact packages (the QG8 code denotes its package). Common applications include microprocessor/data buses, memory interfacing, peripheral buffering, and level-shifting in mixed-voltage systems. For exact electrical characteristics, pinout, timing diagrams, and packaging details, consult the manufacturer’s datasheet or a reputable distributor.

QS3VH253QG8 is a Quad 2-to-1 multiplexer with 3-state outputs (74-series). Possible equivalents (check Vcc, speed, and package):
- TI SN74VH253
- NXP/Nexperia ST 74VHC253 (and related 74VHC253 parts)
- ON Semiconductor MC74VH253
Note: confirm pinout and voltage rating (3.3 V vs 5 V) before substitute.

I don’t have the pin count or function for QS3VH253QG8 memorized. Please provide the manufacturer or a datasheet link. Once I have the datasheet I’ll give you the exact pin count and primary function succinctly.
