MC10E1651 5V, −5V Dual ECL Output Comparator with Latch The MC10E1651 is fabricated using ON Semiconductor’s advanced MOSAIC III™ process. The MC10E1651 incorporates a fixed level of input hysteresis as well as output compatibility with 10 KH logic devices. In addition, a latch is available allowing a sample and hold function to be performed. The device is available in both a 16-pin DIP and a 20-pin surface mount package. The latch enable (LENa and LENb) input pins operate from standard ECL 10 KH logic levels. When the latch enable is at a logic high level, the MC10E1651 acts as a comparator; hence, Q will be at a logic high level if V1 > V2 (V1 is more positive than V2). Q is the complement of Q. When the latch enable input goes to a low logic level, the outputs are latched in their present state providing the latch enable setup and hold time constraints are met.

For example, at 25°C the nominal hysteresis value is 27 mV and the Vskew value indicates that the hysteresis was skewed from the reference level by 1mV in the negative direction. Hence the hysteresis window ranged from 14 mV below the reference level to 13 mV above the reference level. All hysteresis measurements were determined using a reference voltage of 0 mV. http://onsemi.com 3 MC10E1651 Table 5.

Refer to figure 4 and note that the input is at 850mV ECL levels with the input threshold range between the 20% and 80% points. The delay is measured from the crosspoint of the input signal and the threshold value to the crosspoint of the Q and Q output signals. 7. The slew rate is 0.25 V/NS for input rising edges. 8. The slew rate is 0.75 V/NS for input rising edges. 9. Refer to Figure 5 and note that the input is at 2.5 V TTL levels with the input threshold range between the 20% and 80% points. The delay is measured from the crosspoint of the input signal and the threshold value to the crosspoint of the Q and Q output signals. 10. The slew rate is 0.3 V/NS for input rising edges. http://onsemi.com 4 MC10E1651 APPLICATIONS INFORMATION The timing diagram (Figure 3.) is presented to illustrate the MC10E1651’s compare and latch features. When the signal on the LEN pin is at a logic high level, the device is operating in the “compare mode,” and the signal on the input arrives at the output after a nominal propagation delay (tPHL, tPLH). The input signal must be asserted for a time, ts, prior to the negative going transition on LEN and held for a time, th, after the LEN transition. After time th, the latch is operating in the “latch mode,” thus transitions on the input do not appear at the output. The device continues to operate in the “latch mode” until the latch is asserted once again. Moreover, the LEN pulse must meet the minimum pulse width (tpw) requirement to effect the correct input-output relationship. Note that the LEN waveform in Figure 3. shows the LEN signal swinging around a reference labeled VBBINT; this waveform emphasizes the requirement that LEN follow typical ECL 10KH logic levels because VBBINT is the internally generated reference level, hence is nominally at the ECL VBB level. Finally, VOD is the input voltage overdrive and represents the voltage level beyond the threshold level (VTHR) to which the input is driven. As an example, if the threshold level is set on one of the comparator inputs as 80 mV and the input signal swing on the complementary input is from zero to 100 mV, the positive going overdrive would be 20 mV and the negative going overdrive would be 80 mV. The result of differing overdrive levels is that the devices have shorter propagation delays with greater overdrive because the threshold level is crossed sooner than the case of lower overdrive levels. Typically, semiconductor manufactures refer to the threshold voltage as the input offset voltage (VOS) since the threshold voltage is the sum of the externally supplied reference voltage and inherent device offset voltage.

TNOM accounts for nonuniformity introduced by temperature and voltage variability, whereas the delay dispersion parameter takes into consideration input slew rate and input voltage overdrive variability. Thus a modified propagation delay can be approximated to account for the effects of input conditions that differ from those under which the parts where tested. For example, an application may specify an ECL input with a slew rate of 0.25 V/NS, an overdrive of 17 mV and a temperature of 25°C, the delay dispersion parameter would be 100 ps. The modified propagation delay would be 775 ps ± 100 ps Under a constant set of input conditions comparators have a specified nominal propagation delay. However, since propagation delay is a function of input slew rate and input voltage overdrive the delay dispersion parameters, TDE and TDT, are provided to allow the user to adjust for these variables (where TDE and TDT apply to inputs with standard ECL and TTL levels, respectively). Figure 4 and Figure 5 define a range of input conditions which incorporate varying input slew rates and input voltage overdrive. For input parameters that adhere to these constraints the propagation delay can be described as: TNOM ± TDE (or TDT) −0.9 V − 1.07 V INPUT THRESHOLD RANGE 2.5 V 2.0 V SLEW RATE = 0.25 V/NS INPUT THRESHOLD RANGE SLEW RATE = 0.75 V/NS − 1.58 V − 1.75 V SLEW RATE = 0.30 V/NS SLEW RATE = 0.75 V/NS 0.5 V 0V Figure 4.
