Preliminary specification
CBT3244
Octal bus switch with Quad Output Enables
2
1998 Dec 08
FEATURES
Functionally equivalent to QS3244
Standard ’244-type pinout
5
switch connection between two ports
TTL compatible control input levels
Package options include plastic small outline (D), shrink small
outline (DB), thin shrink small outline (TSSOP)
DESCRIPTION
The CBT3244 provides eight bits of high-speed TTL-compatible bus
switching in a standard ’244 device pinout. The low on-state
resistance of the switch allows connections to be made with minimal
propagation delay.
The CBT3244 device is organized as two 4-bit low-impedance
switches with separate output-enable (OE) inputs. When OE is low,
the switch is on and data can flow from port A to port B, or vice
versa. When OE is high, the switch is open and high-impedance
state exists between the two ports.
The CBT3244 is characterized for operation from –40
