74VHC161284
IEEE 1284 Transceiver
General Description
The VHC161284 contains eight bidirectional data buffers
and eleven control/status buffers to implement a full
IEEE 1284 compliant interface. The device supports the
IEEE 1284 standard and is intended to be used in
Extended Capabilities Port mode (ECP). The pinout allows
for easy connection from the Peripheral (A-side) to the
Host (cable side).
Outputs on the cable side can be configured to be either
open drain or high drive (
±
14 mA). The pull-up and pull-
down series termination resistance of these outputs on the
cable side is optimized to drive an external cable. In addi-
tion, all inputs (except HLH) and outputs on the cable side
contain internal pull-up resistors connected to the V
CC
sup-
ply to provide proper termination and pull-ups for open
drain mode.
Outputs on the Peripheral side are standard LOW-drive
CMOS outputs. The DIR input controls data flow on the
