Description

General part information

SN74CB3T16211 Series

The SN74CB3T16211 is a high-speed TTL-compatible FET bus switch with low ON-state resistance (ron), allowing for minimal propagation delay. The device fully supports mixed-mode signal operation on all data I/O ports by providing voltage translation that tracks VCC. The SN74CB3T16211 supports systems using 5-V TTL, 3.3-V LVTTL, and 2.5-V CMOS switching standards, as well as user-defined switching levels.

The I/O port of this device has a pullup current source that maintains the output voltage at VCCwhen the device is ON, and the input is greater than or equal to VCC– 1. Because of the pullup current source, the output voltage level may be less than VCCwhen the operating frequency is low and the I/O port is connected to a pulldown resistor. In order to maintain the output voltage at VCC, a pullup resistor must be connected to VCCinstead of a pulldown resistor to ground.

The SN74CB3T16211 is organized as two 12-bit bus switches with separate output-enable (1OE, 2OE) inputs. It can be used as two 12-bit bus switches or as one 24-bit bus switch. WhenOEis low, the associated 12-bit bus switch is ON, and the A port is connected to the B port, allowing bidirectional data flow between ports. WhenOEis high, the associated 12-bit bus switch is OFF, and a high-impedance state exists between the A and B ports.
