SCAN18374T
D-Type Flip-Flop with 3-STATE Outputs
General Description
The SCAN18374T is a high speed, low-power D-type flip-
flop featuring separate D-type inputs organized into dual 9-
bit bytes with byte-oriented clock and output enable control
signals. This device is compliant with IEEE 1149.1 Stan-
dard Test Access Port and BOUNDARY-SCAN Architec-
ture 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
s IEEE 1149.1 (JTAG) Compliant
s Buffered positive edge-triggered clock
s 3-STATE outputs for bus-oriented applications
s 9-bit data busses for parity applications
s Reduced-swing outputs source 32 mA/sink 64 mA
s Guaranteed to drive 50
transmission line to TTL input
levels of 0.8V and 2.0V
s TTL compatible inputs
s 25 mil pitch SSOP (Shrink Small Outline Package)
s Includes CLAMP and HIGHZ instructions
s Member of Fairchild’s SCAN Products
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
