74LVTH543 - Low Voltage Octal Registered Transceiver

General Description

The LVTH543 octal transceiver contains two sets of D-type latches for temporary storage of data flowing in either direction.

Separate Latch Enable and Output Enable inputs are provided for each register to permit independent control of inputting and outputting in either direction of data flow.

Key Features

  • s Input and output interface capability to systems at 5V VCC s Bushold data inputs eliminate the need for external pullup 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 543 s Latch-up performance exceeds 500 mA Ordering Code: Order Number 74LVTH543WM 74LVTH543MTC Package Number M24B MTC24 Package.

74LVTH543 Low Voltage Octal Registered Transceiver with 3-STATE Outputs April 2000 Revised April 2000 74LVTH543 Low Voltage Octal Registered Transceiver with 3-STATE Outputs General Description The LVTH543 octal transceiver contains two sets of D-type latches for temporary storage of data flowing in either direction. Separate Latch Enable and Output Enable inputs are provided for each register to permit independent control of inputting and outputting in either direction of data flow. The LVTH543 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs. This octal registered transceiver is designed for low-voltage (3.3V) VCC applications, but with the capability to provide a TTL interface to a 5V environment.
