82C87H
CMOS Octal Inverting Bus Transceiver
March 1997
Features
Description
• Full Eight Bit Bi-Directional Bus Interface
• Industry Standard 8287 Compatible Pinout
The Intersil 82C87H is a high performance CMOS Octal
Transceiver manufactured using a self-aligned silicon gate
CMOS process (Scaled SAJI IV). The 82C87H provides a full
eight-bit bi-directional bus interface in a 20 pin package. The
Transmit (T) control determines the data direction. The active
low output enable (OE) permits simple interface to the
80C86, 80C88 and other microprocessors. The 82C87H has
gated inputs, eliminating the need for pull-up/pull-down resis-
tors and reducing overall system operating power dissipation.
The 82C87H provides inverted data at the outputs.
