description

The SN74CBTH16211 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.

1A9

The device is organized as dual 12-bit bus

switches with separate output-enable (OE)

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

or one 24-bit bus switch. When OE is low, the

associated 12-bit bus switch is on, and the A port

is connected to the B port. When OE is high, the

switch is open, and a high-impedance state exists

between the two ports.

Active bus-hold circuitry is provided to hold

unused or floating A and B ports at a valid logic

level.

To ensure the high-impedance state during power

up or power down, OE should be tied to V

through a pullup resistor; the minimum value of

the resistor is determined by the current-sinking

capability of the driver.

NC – No internal connection
