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
