SN74CBT3305C Datasheet Dual Fet Bus Switch

Manufacturer: Texas Instruments

Overview: .ti. SN74CBT3305C DUAL FET BUS SWITCH 5-V BUS SWITCH WITH –2-V UNDERSHOOT PROTECTION SCDS125B – SEPTEMBER 2003 – REVISED AUGUST.

General Description

/ORDERING INFORMATION The SN74CBT3305C is a high-speed TTL-patible FET bus switch with low ON-state resistance (ron), allowing for minimal propagation delay.

Active undershoot-protection circuitry on the A and B ports of the device provides protection for undershoot up to –2 V by sensing an undershoot event and ensuring that the switch remains in the proper OFF state.

The SN74CBT3305C is organized as two 1-bit bus switches with separate output-enable (1OE, 2OE) inputs.

Key Features

  • Undershoot Protection for OFF Isolation on A and B Ports up to.
  • 2 V.
  • Bidirectional Data Flow With Near-Zero Propagation Delay.
  • Low ON-State Resistance (ron) Characteristics (ron = 3 Ω Typ).
  • Low Input/Output Capacitance Minimizes Loading and Signal Distortion (Cio(OFF) = 5 pF Typ).
  • Data and Control Inputs Provide Undershoot Clamp Diodes.
  • Low Power Consumption (ICC = 3 µA Max).
  • VCC Operating Range From 4 V to 5.5 V.
