Description

SN74ALVCH16244DGGR is a 16-bit buffer/driver with 3-state outputs from TI. It contains two 8-bit buffers (Q0–Q7 and Q8–Q15) that are noninverting and can drive a bus, with two active-low enables (1OE and 2OE) to tri-state each 8-bit group. When an OE is low, the corresponding outputs drive; when high, they go High-Z. It includes bus-hold on all data inputs to stabilize floating lines. Operates from 1.65 V to 3.6 V, suitable for low-voltage and mixed-voltage systems. Package DGGR denotes a 20-pin lead-free (green) variant, typically a VSSOP-like form factor. Applications: buffering between buses/ICs, memory interfaces, microcontroller/PLD/ASIC data paths, and general-purpose data buffering where isolated, controllable outputs are needed.

Features

Here are concise features of SN74ALVCH16244DGGR:
- 16-bit buffer/driver with 3-state outputs
- Two 8-bit sections, each with its own output enable
- Noninverting data path (A inputs to Y outputs)
- Advanced Low-Voltage CMOS (ALVCH) technology
- Wide supply range: 1.65 V to 3.6 V (Vcc)
- CMOS input thresholds; suitable for standard CMOS logic levels
- Low static and dynamic current for power efficiency
- High-speed operation with fast propagation delays
- 16-pin TSSOP package (DGGR)
- Suitable for bus buffering, backplane interfaces, and data buffering on mixed-voltage systems

Package

28-pin TSSOP package (DGGR suffix indicates RoHS/green version).

Pinout

- Pin count: 20 pins (TSSOP/VSSOP-20 package, DGGR).
- Function: SN74ALVCH16244DGGR is a 16‑bit buffer/driver with 3‑state outputs, consisting of two independent 8‑bit buffers. Each bank has its own output-enable control, allowing the 16 outputs (Y0–Y15) to be tri-stated when disabled. Data flows from A inputs to Y outputs when enabled.

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI).
- What kind of company: American multinational semiconductor company that designs and manufactures integrated circuits and analog devices; a leading global semiconductor producer.

Application

- 16-bit buffer/driver for data and address buses
- Dual 8-bit buffers with 3-state outputs for bus sharing and isolation
- Interface between microprocessors, memory, ASICs, and FPGAs
- Level shifting between voltage domains (1.65–3.6 V systems)
- IO expansion, backplane/interconnect applications and glue logic in high-speed systems
