82C86H
CMOS Octal Bus Transceiver
March 1997
Features
Description
• Full Eight Bit Bi-Directional Bus Interface
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.

Gated Inputs

N
During normal system operation of a latch, signals on the
bus at the device inputs will become high impedance or
make transitions unrelated to the operation of the latch.
These unrelated input transitions switch the input circuitry
and typically cause an increase in power dissipation in
CMOS devices by creating a low resistance path between
VCC and GND when the signal is at or near the input switching threshold. Additionally, if the driving signal becomes high
impedance (“float” condition), it could create an indeterminate logic state at the inputs and cause a disruption in
device operation.

The Intersil 82C8X series of bus drivers eliminates these
conditions by turning off data inputs when data is latched
(STB = logic zero for the 82C82/83H) and when the device is
disabled (OE = logic one for the 82C86H/87H). These gated
inputs disconnect the input circuitry from the VCC and
ground power supply pins by turning off the upper P-channel
and lower N-channel (See Figures 1 and 2). No current flow
from VCC to GND occurs during input transitions and invalid
logic states from floating inputs are not transmitted. The next
stage is held to a valid logic level internal to the device.
D.C. input voltage levels can also cause an increase in ICC if
these input levels approach the minimum VIH or maximum
VIL conditions. This is due to the operation of the input circuitry in its linear operating region (partially conducting
state). The 82C8X series gated inputs mean that this condition will occur only during the time the device is in the transparent mode (STB = logic one). ICC remains below the
maximum ICC standby specification of 10µA during the time
inputs are disabled, thereby greatly reducing the average
power dissipation of the 82C8X series devices.

This current spike may cause a large negative voltage spike
on VCC which could cause improper operation of the device.
To filter out this noise, it is recommended that a 0.1µF
ceramic disc capacitor be placed between VCC and GND at
each device, with placement being as near to the device as
possible.

NOTES:
1. VIH is measured by applying a pulse of magnitude = VIH(MIN) to one data input at a time and checking the corresponding device output for
a valid logical “1” during valid input high time. Control pins (T, OE) are tested separately with all device data input pins at VCC -0.4
2. Typical ICCOP = 1mA/MHz of read/ cycle time. (Example: 1.0µs read/write cycle time = 1mA).
