SCAN18540T
Inverting Line Driver with 3-STATE Outputs

General Description

The SCAN18540T is a high speed, low-power line driver featuring separate data inputs organized into dual 9-bit bytes with byte-oriented paired output enable control signals. This device is compliant with IEEE 1149.1 Standard Test Access Port and Boundary Scan Architecture with the incorporation of the defined boundary-scan test logic and test access port consisting of Test Data Input (TDI), Test Data Out (TDO), Test Mode Select (TMS), and Test Clock (TCK).

Features

  • IEEE 1149.1 (JTAG) compliant
  • Dual output enable signals per byte
  • 3-STATE outputs for bus-oriented applications
  • 9-bit data busses for parity applications
  • Reduced-swing outputs source 32 mA/sink 64 mA
  • Guaranteed to drive 50ohm transmission line to TTL input levels of 0.8V and 2.0V
  • TTL compatible inputs
  • 25 mil pitch SSOP (Shrink Small Outline Package)
  • Includes CLAMP and HIGHZ instructions
  • Member of Fairchild's SCAN products
