Texas Instruments SN75160BN
The SN75160B 8-channel general-purpose interface bus (GPIB) transceiver is a monolithic, high-speed, low-power Schottky device designed for two-way data communications over single-ended transmission lines. It is designed to meet the requirements of IEEE Standard 488-1978. The transceiver features driver outputs that can be operated in either the passive-pullup or 3-state mode.D Meets IEEE Standard 488-1978 (GPIB) D 8-Channel Bidirectional Transceiver D Power-Up/Power-Down Protection (Glitch Free) D High-Speed, Low-Power Schottky Circuitry D Low Power Dissipation . . . 72 mW Max Per Channel D Fast Propagation Times . . . 22 ns Max D High-Impedance pnp Inputs D Receiver Hysteresis . . . 650 mV Typ D Open-Collector Driver Output Option D No Loading of Bus When Device Is Powered Down (VCC = 0) SN75160B OCTAL GENERAL-PURPOSE INTERFACE BUS TRANSCEIVER SLLS004B – OCTOBER 1985 – REVISED MAY 1995 DW OR N PACKAGE (TOP VIEW) TE 1 B1 2 B2 3 GPIB I/O Ports B3 4 B4 5 B5 6 B6 7 B7 8 B8 9 GND 10 20 VCC 19 D1 18 D2 17 D3 16 D4 15 D5 14 D6 13 D7 12 D8 11 PE Terminal I/O Ports description If talk enable (TE) is high, these ports have the characteristics of passive-pullup outputs when pullup enable (PE) is low and of 3-state outputs when PE is high. Taking TE low places these ports in the high-impedance state. The driver outputs are designed to handle loads up to 48 mA of sink current.
