SN74LVC16245ADGGR

The SN74LVC16245A is a 16-bit (dual-octal) non-inverting bus transceiver from Texas Instruments, part of the Widebus™ family. It is designed for asynchronous communication between data buses and operates from a supply voltage of 1.65 V to 3.6 V, while its inputs can accept voltages up to 5.5 V. This transceiver can function as two independent 8-bit transceivers or one 16-bit transceiver.

Key electrical characteristics include a maximum propagation delay (tpd) of 4 ns at 3.3 V. It offers typical output ground bounce (VOLP) of less than 0.8 V and typical output VOH undershoot (VOHV) greater than 2 V at 3.3 V and 25°C. The device supports mixed-mode signal operation on all ports, allowing 5-V input/output voltage with a 3.3-V VCC. It also features Ioff support for live insertion, partial-power-down mode, and back-drive protection.

Designed for reliability, the SN74LVC16245A exhibits latch-up performance exceeding 250 mA per JESD 17 and ESD protection exceeding JESD 22 standards, including 2000-V HBM, 200-V MM, and 1000-V CDM. The operating temperature range is -40°C to 125°C (TA).

This device is available in a 48-TSSOP package with dimensions of 12.50 mm × 6.10 mm. Other package options include TVSOP (9.70 mm × 4.40 mm) and SSOP (15.88 mm × 7.49 mm). Its applications span electronic points of sale, printers, motor drives, wireless and telecom infrastructures, and wearable health and fitness devices.
