RC7311

The RC7311 Pin Electronics Driver is an economical alternative to standard pin electronics drivers in applications that do not require three state capability in the driver. An example of such an application would be the large number of input address pins found in memory testers.The driver output levels are programmable between -3.0V and +8V to drive ECL, TTL and CMOS logic families. The peak to peak output swing can vary from values lower than 300mV to values as high as 10V. With toggle rates greater than 250MHz for ECL signals and typical slew rates of 2 V/ns for 5 Vp-p signal amplitudes, the RC7311 is comparable with the requirements of state-of-the-art testers. The high and low limits of the output swing are set through the program pins VH and VL, respectively. The transfer characteristic from the program pins to the output pin is unity gain with low offset (30mV) and offset drift (0.1 mV/OC typical). The VH and VL inputs have been buffered to operate with low bias currents (1.0 uA typical) allowing direct coupling to the output of a DAC. The RC7311 is provided with high speed differential ECL inputs for ease of interface with the differential ECL outputs of a timing generator. The inputs have a wide voltage range, -2V to +6V, so that if required, an input may be driven by TTL or CMOS devices provided that the other input is tied to the appropriate threshold value.

The features of RC7311 can be summarized as (1)high output slew rate (1.8 V/ns typical); (2)wide output voltage range to and up to 10 Vp-p swings; (3)250MHz minimum operation for ECL swings; (4)wide input common mode range for ease of interface to ECL as well as TTL and CMOS; (5)output short-circuit protection with current limiter and thermal shutdown; (6)100mA dynamic switching current drive; (7)absolute slew rate control; (8)available in 28-Lead PLCC; (9)low output voltage offset (30mV) and output offset drift (0.1 mV/°C typ.); (10)low input bias current (1 A typical) and current drift (40 nA/°C) for output level program allows direct coupling to a DAC output.

The absolute maximum ratings of RC7311 are (1)positive power supply, VCC:13V; (2)negative power supply, VEE:-8.2V; (3)difference between VCC and VEE: 16V; (4)input voltage at VlN+VlN-, lNH+, INH-: VCC-12 to VEE+12 V; (5)input voltage at VH, VL: VCC-13  to VEE+13V; (6)difference between VH & VL:13V; (7)operating tmperature rang 0 to 70°C; (8)lead temperature range (soldering 10 seconds):300°C; (9)driver output voltage:  VCC-13 to VEE+13; (10)output voltage at TS: 7V; (11)duration of short-circuit to ground: indefinite; (12)operating temperature range: 70°C; (13)storage temperature range: -65°C +125°C.("Absolute maximum ratings" are those beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the device should be operated at these limits. If the device is subjected to the limits in the absolute maximum ratings for extended periods, its reliability may be impaired.
