SN74LVCH244ARGYR

SN74LVCH244ARGYR is an 8-bit buffer/line driver with two 4-bit tri-state sections. It buffers data from inputs A1–A8 to outputs Y1–Y8, with separate output-enable pins (OE1 and OE2) to put each 4-bit group in high-impedance when disabled. It belongs to TI’s LVCH family, designed for low-voltage CMOS operation and high-speed performance.
Key points:
- 8 non-inverting buffers, two 4-bit sections with independent enables
- 3-state outputs (Hi-Z when disabled)
- Operating voltage: typically 1.65 V to 3.6 V (suitable for 1.8–3.3 V logic domains)
- Suitable for bus buffering, data isolation, and level-shifting between logic families
- CMOS inputs with standard thresholds; low static power
- RoHS-compliant lead-free packaging (suffix G/YR indicates a green, RoHS-compliant option; packaging type indicated by suffix)
For exact electrical specs (Vih/Vil, VOL/VOH, tPD, current limits) and pinout, consult the current TI SN74LVCH244A datasheet.

Equivalent devices (8-bit octal buffer/driver with 3-state outputs, 2.7–5.5 V):
- Nexperia (formerly NXP/Philips): 74LVCH244 (e.g., 74LVCH244APW)
- Onsemi: MC74LVCH244 (MC74LVCH244A)
- TI: SN74LVC244A (pin-compatible in many packages)
- ST: 74LVC244A (where available)
Note: verify exact package, drive strength, and Vcc-range; electrical characteristics can vary slightly.

Here are the key features of SN74LVCH244ARGYR:
- 8-bit buffer/line driver with 3-state outputs (A inputs to Y outputs)
- Two independent 4-bit buffer banks with separate enables: 1OE and 2OE (active LOW)
- Noninverting buffers
- Wide operating voltage: LVCH family (typically 1.65 V to 3.6 V)
- CMOS input thresholds with good noise margins; suitable for 3.3-V and lower systems
- Low static/dynamic power consumption
- Outputs go High-Z when disabled for bus sharing
- Standard 20-pin package (ARGYR is the TI packaging code for that variant)
- Suitable for data/address bus buffering and level‑shifting in low‑power designs
Note: Always check the exact voltage range and ratings in the datasheet for your exact lot/package.

- Pin count: 20 pins
- Function: Octal buffer/driver with 3-state outputs (A0–A7 to Y0–Y7) with bidirectional data flow controlled by DIR and an OE input to enable/tri-state the outputs. Used as a bus buffer/buffer driver.

The SN74LVCH244ARGYR is manufactured by Texas Instruments (TI). TI is an American multinational technology company that designs and manufactures semiconductors and integrated circuits (analog and digital ICs).

- An 8-bit, non-inverting buffer/line driver with 3-state outputs.
- Used to interface CPUs/MCUs with memory and peripherals (data, address, and control lines).
- Ideal for bus buffering and signal distribution on shared buses with tri-state enable.
- Provides signal isolation and fan-out expansion for high-speed, low-voltage digital paths.
- Suitable for portable/embedded systems, backplanes, and other interconnects requiring reliable drive and bus control.

The SN74LVCH244ARGYR comes in a 20-pin TSSOP (Thin Shrink Small-Outline) package, RoHS-compliant.
