SN74GTL1655DGGR — Overview
SN74GTL1655DGGR by Texas Instruments is a component in the 16-bit LVTTL-to-GTL/GTL+ UBT Transceiver with Live Insertion category, supplied by Shenzhen Jinteng Electronics Technology Co., Ltd. (JTDZ Tech) — an independent distributor serving OEMs, ODMs and EMS providers worldwide.
The SN74GTL1655DGGR is a 16-bit universal bus transceiver that translates between LVTTL logic on the card side and GTL/GTL+ signal levels on the backplane side, partitioned as two independent 8-bit words with D-type latches and flip-flops for transparent, latched or clocked operation. Its B port sinks 100 mA with 12 ohm output impedance for double-terminated low-impedance backplanes, and the VERC pin adjusts output edge rates. Ioff, power-up 3-state and BIAS VCC precharge support true live insertion.

Parameters above are transcribed from the manufacturer datasheet for reference only. Confirm the current datasheet revision and your application conditions before design-in.
Note: Two corrections to the brief: (1) the DGG package is a 64-pin TSSOP measuring 17.0 x 8.1 mm, not TSSOP-56; (2) this device does NOT provide IEEE 1149.1 boundary scan - TI datasheet SCBS696I lists UBT, OEC, bus hold and live insertion, but no JTAG TAP or boundary-scan register. 'R' suffix = large tape and reel (2000 pcs).
