描述 Description

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 resistors and reducing overall system operating power dissipation.

The 82C87H provides inverted data at the outputs.
