The HIT interfaces directly with Scheme and, is 100% compatible with all existing Standard Microsystems Corporation's ARCNET coax-based ARCNET networks. This provides an LAN controllers operating at 2.5 Mbps and ARCNET network designer with flexibility to easily connects to a variety of shielded and unshielded combine coax and twisted pair cabling. twisted pair or coaxial cables via an on-board transformer. The network topologies supported by The HYC9088 is pin compatible with the HYC9058 the HIT are daisy chain, star, and bus High Impedance Transceiver and is pin compatible configurations. with the HYC9068 LAN Driver with the addition of a single terminating resistor. During data transmission, the HIT converts the digital pulse information provided by the LAN controller into analog signals and drives them onto the cable. The transmitted signals are filtered to eliminate undesirable frequencies. The receiver section of the HYC9088 identifies dipulse signals ee DataSh DataSheet4U.com DataSheet4U.com DataSheet 4 U .com www.DataSheet4U.com TABLE OF CONTENTS FEATURES...................................................................................................................................................... 1 GENERAL DESCRIPTION.............................................................................................................................. 1 PIN CONFIGURATION.................................................................................................................................... 3 DESCRIPTION OF PIN FUNCTIONS............................................................................................................ 4 FUNCTIONAL DESCRIPTION........................................................................................................................ 5 APPLICATION INFORMATION ..................................................................................................................... 5 OPERATIONAL DESCRIPTION .................................................................................................................. 11 MAXIMUM GUARANTEED RATINGS.......................................................................................... 11 DC ELECTRICAL CHARACTERISTICS...................................................................................... 11 m et4U.co ee DataSh DataSheet4U.com 2 DataSheet4U.com DataSheet4U.com DataSheet 4 U .com www.DataSheet4U.com PIN CONFIGURATION Pin 1 Designator 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 NC NC VDD GND NC VCC RX TPA NC TPD PH-B/SHIELD PH-A/CENTER GND GND TPC TPB GND T O P V I E W m et4U.co 18 nPULSE2 DataSheet4U.com 19 DISABLE 20 nPULSE1 ee DataSh PACKAGE: 20-Pin SIP Ordering Information: HYC9088AR for right angle lead frame HYC9088AS for straight lead frame 3 DataSheet4U.com DataSheet4U.com DataSheet 4 U .com www.DataSheet4U.com DESCRIPTION OF PIN FUNCTIONS PIN NO. 1, 2, 5, 9 3 4, 13, 14, 17 6 7 8, 16, 15, 10 11 12 18 19 20 NAME No Connect Power Supply Ground Power Supply Receive Data Test Points Phase-B/ Shield Phase-A/ Center nPulse 2 Disable TX nPulse 1 SYMBOL NC VDD GND VCC RX TPA, TPB, TPC, TPD PH-B/ SHIELD PH-A/ CENTER nPULSE2 DISABLE TRANSMIT nPULSE1 -5 Volts power supply.
