SNx4CBT3383 10-Bit Bus-Exchange Switch

1 Features

• High-Bandwidth Data Path (Up to 200 MHz)
• Low and Flat ON-State Resistance (r_ON) Characteristics Over Operating Range
  (r_ON = 5 Ω Typical)
• Control Inputs Can Be Driven by TTL or 5-V and 3.3-V CMOS Outputs
• Bidirectional Data Flow With Near-Zero Propagation Delay
• Low Input and Output Capacitance Minimizes Loading and Signal Distortion (C_io(OFF) = 6 pF Typical)
• V_CC Operating Range From 4.5 V to 5 V
• Low Power Consumption (I_CC = 50 µA Maximum)

2 Applications

• Enterprise Servers
• Ethernet Switches
• Routers
• Servers
• Industrial PCs

3 Description

The SN74CBT3383 and SN54CBT3383 devices provide ten bits of high-speed TTL-compatible bus switching or exchanging. The low ON-state resistance of the switch allows connections to be made with minimal propagation delay.

The devices operate as a 10-bit bus switch or a 5-bit bus exchanger, which provides swapping of the A and B pairs of signals. The bus-exchange function is selected when BX is high. The switches are connected when BE is low.
