SN74CB3T16210DGGR

产品概述

The SN74CB3T16210DGGR 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. It supports systems using 5V TTL, 3.3V LVTTL and 2.5V CMOS switching standards, as well as user-defined switching levels. It is organized as two 10-bit bus switch with separate OE inputs. It can be used as two 10-bit bus switches or as one 20-bit bus switch. When OE is low, the associated 10-bit bus switch is ON and the A port is connected to the B port, allowing bidirectional data flow between ports. When OE is high, the associated 10-bit bus switch is OFF and a high-impedance state exists between the A and B ports. This device is fully specified for partial-power-down applications using Ioff. The Ioff feature ensures that damaging current will not backflow through the device when it is powered down.
