SM8530B

The SM8530B is a CMOS LSII designed specifically to offer a standardized interface bus meeting the IEC standard and a measuring equipment interface on a single chip and this IC executes 3-line handshaking, address commands and bus line commands without software support. Standardized interface functions complying with the IEC standard can be realized easily by adding several extemal circuits and a bus line driver/receiver. [Note] The LSI is also applicable to the IEEE-488, HP-IB and GP-IB.

The features of SM8530B can be summarized as (1)the SM8530B does not require a microprocessor, hence: 1) software development is not necessary, 2) the CPU of measuring equipment can be used effectively, 3) A standardized interface function can be added easily to an existing measuring equipment; (2)output pins corresponding to interface states (TLK, LSN, RMT, CLR, TRG, etc.) are provided to facilitate operation and increase response speed; (3)low current consumption realized by CMOS construction; (4)easy address setting with extemal switches; (5)three-line handshaking can be controlled only with the HS-ENB* signal; (6)output pins (BSY, RG-CLK, etc.) for controlling extemal circuits simplify peripheral circuits.

The absolute maximum ratings of SM8530B are (1)supply voltage VDD=VSS: -3.0 to +7.0V; (2)input voltage VIN: VSSVINVDD V; (3)operating temperature TOPF: 0 to +70°C; (4)storage temperature Tstg: -40 to +125°C.
