74LVTH16646 - Low Voltage 16-Bit Transceiver/Register

General Description

The LVTH16646 contains sixteen non-inverting bidirectional registered bus transceivers providing multiplexed transmission of data directly from the input bus or from the internal storage registers.

Each byte has separate control inputs which can be shorted together for full 16-bit operation.

Key Features

  • s Input and output interface capability to systems at 5V VCC s Bushold data inputs eliminate the need for external pull-up resistors to hold unused inputs s Live insertion/extraction permitted s Power Up/Down high impedance provides glitch-free bus loading s Outputs source/sink.
  • 32 mA/+64 mA s Functionally compatible with the 74 series 16646 s Latch-up performance exceeds 500 mA Ordering Code: Order Number 74LVTH16646MEA 74LVTH16646MTD Package Number MS56A MTD56 Package.

74LVTH16646 Low Voltage 16-Bit Transceiver/Register with 3-STATE Outputs January 2000 Revised January 2000 74LVTH16646 Low Voltage 16-Bit Transceiver/Register with 3-STATE Outputs General Description The LVTH16646 contains sixteen non-inverting bidirectional registered bus transceivers providing multiplexed transmission of data directly from the input bus or from the internal storage registers. Each byte has separate control inputs which can be shorted together for full 16-bit operation. The DIR inputs determine the direction of data flow through the device. The CPAB and CPBA inputs load data into the registers on the LOW-to-HIGH transition (see Functional Description). The LVTH16646 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.
