Product details

What this I²C accelerator does on the bus

The LTC1694IS5#TRM is a single-channel buffer and accelerator for 2-wire buses like I²C and SMBus. It sits between the master and the bus capacitance, actively driving the rising edge to meet the 400 kHz data rate without stretching the clock low time. Supply range of 2.7 V to 6 V covers both logic families, and the 60 µA quiescent current keeps the power budget tight in always-on bus segments.

Housed in a 5-lead TSOT-23-5 package (1.6 mm × 2.9 mm body), it fits tight PCB layouts where a larger SOIC-8 would crowd adjacent passives.

Frequently asked questions

LTC1694IS5#TRM vs LTC1694-1 — what is the difference?

The LTC1694-1IS5#TRPBF is a lower-speed variant rated for 100 kHz maximum data rate, while the LTC1694IS5#TRM supports 400 kHz. Both share the same TSOT-23-5 package, supply range, and 60 µA supply current. Choose the LTC1694-1 if your bus runs at standard-mode (100 kHz) only; the LTC1694IS5#TRM covers both standard and fast-mode.
