74LCX646 - Low Voltage Octal Transceiver/Register

Description

The LCX646 consists of registered bus transceiver circuits, D-type flip-flops, and control circuitry providing multiplexed transmission of data directly from the input bus or from the internal storage registers.

Features

  • s 5V tolerant inputs and outputs s 2.3V.
  • 3.6V VCC specifications provided s 7.0 ns tPD max (VCC = 3.3V), 10 µA ICC max s Power down high impedance inputs and outputs s Supports live insertion/withdrawal (Note 1) s ±24 mA output drive (VCC = 3.0V) s Implements patented noise/EMI reduction circuitry s Latch-up performance exceeds 500 mA s ESD performance: Human body model > 2000V Machine model > 200V Note 1: To ensure the high-impedance state during power up or down, OE should be tied to.

74LCX646 Low Voltage Octal Transceiver/Register with 5V Tolerant Inputs and Outputs February 1994 Revised April 1999 74LCX646 Low Voltage Octal Transceiver/Register with 5V Tolerant Inputs and Outputs General Description The LCX646 consists of registered bus transceiver circuits, D-type flip-flops, and control circuitry providing multiplexed transmission of data directly from the input bus or from the internal storage registers. Data on the A or B bus will be loaded into the respective registers on the LOW-to-HIGH transition of the appropriate pin (CPAB or CPBA)(see Functional Description). The LCX646 is designed for low voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment.
