SN74LVCH244ARGYR

SN74LVCH244ARGYR is an octal buffer/driver with 3-state outputs from TI’s LVCH family. Key points:
- Function: Buffers eight data lines (A inputs to Y outputs) with two independent output-enable inputs. When both enables are active, data passes; when either enable is inactive, the outputs go high-impedance.
- Voltage and family: Low-voltage CMOS device, typically operates from Vcc = 1.65–3.6 V; CMOS input thresholds; fast, low-power operation.
- Direction and type: Unidirectional data path (A → Y); not a bidirectional transceiver.
- Package: 20-pin small-outline package with RoHS/green packaging; suffix ARGY indicates specific packaging variant; TYR indicates tape-and-reel options.
- Applications: Useful for buffering and isolating an 8-bit data bus, bus interfacing between a microcontroller/ FPGA and peripherals, or expanding I/O without loading the driving source.
- Notes: Ensure both enable inputs are properly driven to avoid contention or bus conflicts.
For exact electrical specs (tpd, VOL/VOH, IL, etc.) and pinout, consult the TI datasheet.

Key features of SN74LVCH244ARGYR:
- Octal buffer/line driver with 3-state outputs (A inputs to B outputs)
- Non-inverting; two 4-bit sections with independent enables
- Two active-low output-enable inputs (OE1 and OE2) for each 4-bit group
- 3-state outputs when disabled; data outputs high-impedance when OE is inactive
- Bus-hold on data inputs to stabilize floating lines
- Ioff (partial-power-down) protection to prevent back-powering
- Wide LV operation: Vcc typically 1.65 V to 3.6 V
- CMOS design with good noise margin and low power
- Packaging: ARGYR (20-pin), suitable for compact PCB layouts
Optional: industrial temperature range and ESD protection are typical but verify specific datasheet if needed.

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

- Pin count: 20 pins (SOIC-20/TSSOP-20 packaging).
- Function: SN74LVCH244A is an octal buffer/line driver with 3-state outputs. It has eight inputs (A1–A8) and eight outputs (Y1–Y8) with two separate 4-bit output-enable inputs (1G and 2G). Enables are active-low; when a G input is LOW, the corresponding four outputs reflect the inputs; when HIGH, those outputs go high-impedance.

Manufacturer: Texas Instruments (TI).
Type of company: An American multinational semiconductor design and manufacturing company that produces integrated circuits and electronic components (analog, digital, and embedded processing ICs).

SN74LVCH244ARGYR is an 8-bit buffer/line driver with 3-state outputs. Typical applications:
