CBT1621 124-bit bus switch with 12-bit output enables

FEA TURES

•5 Ω switch connection between two ports

•TTL compatible control input levels

•Package options include plastic shrink small outline (SSOP),

thin shrink small outline (TSSOP)

•ESD protection exceeds 1000 V CDM per JESD22-C101

•Latch-up testing is done to JESDEC Standard JESD78 which

DESCRIPTION

The CBT16211 provides 24 bits of high-speed TTL-compatible bus
switching. The low on-state resistance of the switch allows
connections to be made with minimal propagation delay.

The device is organized as a dual 12-bit bus switch with separate
output-enable (OE
or as one 24-bit bus switch. When OE
bus switch is on, and port A is connected to port B. When OE
high, the switch is open, and a high-impedance state exists between
the ports.

) inputs. It can be used as two 12-bit bus switches

The CBT16211 is characterized for operation from –40 to 85 °C.
