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.


Design Tip

Are the Schottky clamp diodes required on the outputs when not driving MOSFETs?
