Description for the BUF16821-Q1

The BUF16821-Q1 offers 16 programmable gamma channels and two programmable VCOM channels. The final gamma and VCOM values can be stored in the on-chip, nonvolatile memory. To allow for programming errors or liquid crystal display (LCD) panel rework, the device supports up to 16 write operations to the on-chip memory.

The device has two separate memory banks, allowing simultaneous storage of two different gamma curves to facilitate switching between gamma curves. All gamma and VCOM channels offer a rail-to-rail output that typically swings to within 150 mV of either supply rail with a 10-mA load. All channels are programmed using an I2C interface that supports standard operations up to 400 kHz and high-speed data transfers up to 2.7 MHz.

The device is manufactured using Texas Instruments’ proprietary, state-of-the-art, high-voltage CMOS process. This process offers very dense logic and high supply voltage operation of up to 20 V. The device is offered in an HTSSOP-28 PowerPAD package, and is specified from –40°C to +85°C.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
