SN74LVTH162244DLR

SN74LVTH162244DLR is a 16-bit buffer/driver with three-state outputs from TI. It provides two 8-bit sections (A0–A15 inputs and Y0–Y15 outputs) with independent output-enable controls, allowing the device to buffer a data bus and tri-state the outputs as needed.
Key points:
- Non-inverting buffer: data on A pins appears on Y pins when enabled.
- Two output-enable inputs (one per 8-bit bank) control tri-state outputs.
- LV logic: designed for low-voltage CMOS/TTL-compatible inputs; suitable for interfacing between devices that run at similar or different logic levels.
- Applications: buffering or isolating data buses, expanding I/O, memory/microcontroller interfacing.
- Package: 20-pin small-outline/package variant (DLR indicates a RoHS-compliant lead-free package option).
Note: This device does not function as a bidirectional transceiver; it is a straight-through buffer with tri-state outputs. For exact electrical specs and active-low/high control details, consult the SN74LVTH162244DLR datasheet.

Possible equivalents (16-bit buffer/driver with two 3-state enables):
- MC74LVTH162244 (ON Semiconductor)
- 74LVTH162244 (Nexperia, formerly Philips/NXP)
- 74LVC162244 (STMicroelectronics) – similar LV family, check timing/voltage specs for compatibility
Note: Always verify VCC, input/output levels, and OE pin mapping for cross-compatibility.

SN74LVTH162244DLR Features:
- 16-bit buffer/driver with 3-state outputs
- Two 8-bit sections controlled by separate output enables (G1 and G2)
- 1.65 V to 3.6 V operating voltage (LVTTL/CMOS compatible)
- Ioff supports partial-power-down (no back-powering when Vcc = 0)
- Bus-hold on all data inputs to stabilize floating inputs
- Noninverting buffers; high-impedance outputs when disabled
- Low static and dynamic power consumption
- Suitable for wide-bus interfacing and bus sharing in mixed-voltage systems
- Pb-free package (DLR) with standard small-outline form factor
These features make it ideal for buffering and gating large data buses in portable or low-power digital designs.

- Pin count: 40 pins (SOIC/DIP-40 typical).
- Function: SN74LVTH162244DLR is a 16‑bit buffer/driver with 3‑state outputs. It contains two 8‑bit non-inverting buffers (A0–A7 → Y0–Y7 and A8–A15 → Y8–Y15) with independent, active‑low output enables (OE1 and OE2). When the enables are deasserted, the outputs go high-impedance. Includes Vcc and GND pins.

- Manufacturer: Texas Instruments (TI).
- What kind of company: TI is an American multinational technology company that designs and manufactures semiconductors and analog/digital integrated circuits.

SN74LVTH162244DLR is a 16-bit, tri-state buffer/driver. Typical application areas:
- Buffers for CPU/memory/I/O buses (16-bit data/address paths)
- Bus isolation and expansion in microcontroller/FPGA-based systems
- Interface between 3.3V logic and 5V logic (level compatibility)
- Backplane or peripheral bus buffering to improve signal integrity
- Independent 8-bit sections for bus multiplexing or daisy-chaining applications
