7.4 Device Functional Modes

The TCA39416 device has two functional modes, enabled and disabled. To disable the device, set the OE input low, which disables the rise time and fall time accelerators, and prevents signals from propagating across the channels. The internal pull up resistors are also affected by the OE input and are disabled when OE input is low. Setting the OE input high enables the device. The internal pull-up resistors act has High-Keeper and are enabled based on respective VCC voltage when bus is high. Table 7-1 provides functional description for TCA39416.

Table 7-1 Functional table
Supply voltage(4) Input(1) I/O
VCCA VCCB OE(2)
0.72 V to 1.98 V 0.72 V to 1.98 V L disconnected
0.72 V to 1.98 V 0.72 V to 1.98 V H A1 = B1; A2 = B2
GND(3) GND(3) X disconnected
(1) H = HIGH voltage level; L = LOW voltage level; X = don’t care
(2) OE is referenced to VCCA. Pull OE low to place all outputs in 3-state mode.
(3) When either VCCA or VCCB is at GND level, the device goes into power-down mode.
(4) VCCA ≤ VCCB.
