The Giddings \u0026amp; Lewis brand logo is printed on the board. The board is a large-format, high-density through-hole assembly configured for four independent servo channels labeled SERVO CHAN A, B, C, and D along the left edge. Gold-edge card connectors labeled BOARD and P1 are located along the board edges. A Burr-Brown AMNDAC80-CB1-V D\/A converter IC is visible on the board. Primary analog multiplexer ICs are Texas Instruments DG508ACJ at IC-1, IC-2, IC-44, IC-64, IC-74, IC-79, and additional positions, with T8730 and T8712 date codes, representing a production variant substituting TI DG508ACJ devices in place of the Intersil IH6108CPE used in earlier revisions. Texas Instruments TL082CP dual op-amps branded 722 X B are present at multiple positions. NE5532 and NE5532P precision op-amps appear at IC-32, IC-54, and IC-76. Linear Technology LT1055 op-amps are present at IC-69, IC-77, and IC-82. Logic ICs include P8730A DM74LS174N, P8730A DM74LS244N, SN74LS640N, SN74LS240N, SN74LS138N, SN74LS123N, SN74LS04N, DM74LS08N, SP8730A DM74LS73AN, SN74LS682N, PB504A DM74LS20N, SP8632A DM74LS164N, and DM7406N among others. MC74F32NDS and MC74F174NDS fast logic ICs are present. Test points TP1, TP2, and GND TP9 are accessible. Physical condition shows signs of prior installation and use.\u003c\/p\u003e\n\n\u003cp\u003eStock # 0226-529\u003c\/p\u003e","brand":"Giddings \u0026 Lewis Electronics","offers":[{"title":"Default Title","offer_id":48856762941680,"sku":"m00529","price":899.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6648\/7280\/files\/057E71D6-26D7-49E5-B7B9-70F0B78B4000.jpg?v=1771627363","url":"https:\/\/mroexchange.com\/products\/giddings-lewis-servo-board-pcb-assembly-501-03852-00-502-03055-00-0226-529","provider":"MRO Exchange","version":"1.0","type":"link"}
