Description
The Intersil 82C86H is a high performance CMOS Octal
Transceiver manufactured using a self-aligned silicon gate
CMOS process (Scaled SAJI IV). The 82C86H provides a full
eight-bit bi-directional bus interface in a 20 lead 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 82C86H has gated
inputs, eliminating the need for pull-up/pull-down resistors and
reducing overall system operating power dissipation.
