NOTE: If the input high-voltage (VIH) level is greater than or equal to VCC 1 V and less than or equal to 5.5 V, the
output high-voltage (VOH) level is equal to approximately the VCC voltage level.
SN74CB3T16212
24-BIT FET BUS-EXCHANGE SWITCH, 2.5-V/3.3-V LOW-VOLTAGE BUS SWITCH
WITH 5-V-TOLERANT LEVEL SHIFTER
SCDS157A – OCTOBER 2003 – REVISED FEBRUARY 2005
Figure 1. Typical DC Voltage Translation Characteristics
The SN74CB3T16212 operates as a 24-bit bus switch or as a 12-bit bus exchange that provides data
exchanging between four signal ports. The select (S0, S1, S2) inputs control the data path of the bus-exchange
switch. When the bus-exchange switch is ON, the A port is connected to the B port, allowing bidirectional data
flow between ports. When the bus-exchange switch is OFF, a high-impedance state exists between the A and B
ports.
This device is fully specified for partial-power-down applications using I
off. The Ioff feature ensures that damaging
current will not backflow through the device when it is powered down. The device has isolation during power off.
To ensure the high-impedance state during power up or power down, each select input should be tied to GND
through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of
the driver.
