Edge819 Octal, 18V Pin Electronics Driver TEST AND MEASUREMENT PRODUCTS Description Features The Edge819 is an octal pin electronics driver fabricated in a wide voltage CMOS process. It is designed specifically for Test During Burn In (TDBI) applications, where cost, functional density, and power are all at a premium. • • • • • 18V I/O Range 50 MHz Operation Per Pin Flexibility Flex In Digital Inputs Small footprint (100 pin MQFP) The Edge819 incorporates eight channels of programmable drivers into one 14 mm X 20 mm 100 pin MQFP package. Each channel has per pin driver levels, data, and high impedance control. The Edge819 uses "Flex In" digital inputs and, therefore, can mate directly with any digital technology. Applications The Edge819 is pin and functionally compatible with the Edge818, except the Edge819 does not have any comparators. • Burn In ATE • Low Cost ATE • Instrumentation The 18V driver output range allows the Edge819 to interface directly with TTL, ECL, CMOS (3.3V and 5V), LVCMOS, and custom level circuitry, as well as the high voltage (Super Voltage) level required for many special test modes for Flash Devices.

There are no shared lines between any drivers. The EN* and DATA signals are wide voltage high impedance analog inputs capable of receiving digital signals over a wide common mode range. VBB is the high impedance analog input which sets the threshold for EN* and DATA. VH and VL define the logical "1" and "0" levels of the driver, and can be adjusted anywhere over the range determined by VCC and VEE. There are no restrictions between VH and VL, other than they must remain within the power supply levels. EN*, DATA > VBB < VBB Status "1" "0" DATA X 1 0 In a functional testing environment, where a resistor is added in series with the driver output to create a 50Ω driver, the Edge819 can withstand a short to any legal voltage for an indefinite amount of time. In a low impedance application, with no additional output resistance, the system should be designed to check for a short circuit prior to connecting the driver, and tristate the driver if a short is detected. DOUT HiZ VH VL 2004 Semtech Corp. / Rev. 2, 8/16/04 VH ≤ VCC VL ≤ VCC Driver Output Protection With EN* high, the driver goes into a high impedance state. With EN* low, DATA high forces the driver into a high state, and DATA low forces the driver into a low state. EN* 1 0 0 VEE ≤ VEE ≤ 4 www .semtech.com Edge819 TEST AND MEASUREMENT PRODUCTS Application Information Power Supply Decoupling VCC and VEE should be decoupled to GND with a .1 µF chip capacitor in parallel with a .001 µF chip capacitor. A VCC and VEE plane, or at least a solid power bus, is recommended for optimal performance. The three diode configuration shown in Figure 1 should be used on a once-per-board basis. VH and VL Decoupling VCC External Logic Supply As the VH and VL inputs are unbuffered and supply the driver output current, which can be quite large during edge transitions, decoupling capacitors for these inputs are recommended in proportion to the amount of output current requirements. VDD 1N5820 or Equivalent For applications where VH and VL are shared over multiple channels, a solid power plane to distribute these levels is preferred. External System Ground VEE VBB The two VBB pins are connected together on-chip. Therefore, only one VBB needs to be connected to for proper 819 operation. The two pins may be used to daisy chain a VBB signal across a PC Board without having to route the actual signal underneath the 819. Power Supplies The Edge819 has several power supply requirements to protect the part in power supply fault situations, as well as during power up and power down sequences. The following power supply requirements must be satisifed at all times: Figure 1. Power Supply Protection Scheme Warning: It is extremely important that the voltage on any device pin does not exceed the range of VEE –0.5V to VCC +0.5V at any time, either during power up, normal operation, or during power down. Failure to adhere to this requirement could result in latchup of the device, which could be destructive if the system power supplies are capable of supplying large amounts of current. Even if the device is not immediately destroyed, the cumulative damage caused by the stress of repeated latchup may affect device reliability.
