100393 Low Power 9-Bit ECL-to-TTL Translator with Latches February 1990 Revised November 1999 100393 Low Power 9-Bit ECL-to-TTL Translator with Latches General Description The 100393 is a 9-bit translator for converting F100K logic levels to TTL logic levels. A LOW on the latch enable (LE) latches the data at the input state. A HIGH on the LE makes the latches transparent. A HIGH on either the ECL or TTL output enable (OE ECL or OE TTL), holds the outputs in a high impedance state. The 100393 is designed with TTL, 64 mA outputs for Bus Driving capability. All ECL inputs have 50 kΩ pull-down resistors. When the inputs are either unconnected or at the same potential, the outputs will go LOW. Features s 64 mA IOL drive capability s 2000V ESD protection s −4.2V to −5.7V operating range s Latched outputs s TTL outputs Ordering Code: Order Number 100393QC Package Number V28A Package Description 28-Lead Plastic Lead Chip Carrier (PLCC), JEDEC MO-047, 0.450 Square Devices also available in Tape and Reel.

The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum rating. The “Recommended Operating Conditions” table will define the conditions for actual device operation. Note 2: ESD testing conforms to MIL-STD-883, Method 3015.

Since these “worst case” values normally occur at the temperature extremes, additional noise immunity and guard banding can be achieved by decreasing the allowable system operating ranges. Conditions for testing shown in the tables are chosen to guarantee operation under “worst case” conditions. 3 www.fairchildsemi.com 100393 AC Electrical Characteristics VEE = −4.2V to −5.7V, VCC = GND, VTTL = +4.5V to +5.5V Symbol tPLH tPHL tPLH tPHL tPZH tPZL tPHZ tPLZ tPZH tPZL tPHZ tPLZ tS tH tPW (L) Parameter Propagation Delay Data to Output Propagation Delay LE to Output Output Enable Time OE TTL ↓ to QN Output Disable Time OE TTL ↑ to QN Output Enable Time OE ECL ↑ to QN Output Disable Time OE ECL ↓ to QN Setup Time, DN to LE Hold Time, DN to LE Pulse Width LOW, LE TC = 0°C Min 2.3 2.3 2.0 3.5 2.0 2.0 2.4 3.2 2.4 3.2 0.7 1.3 2.0 Max 4.8 5.6 5.5 8.0 6.0 5.5 5.6 8.5 6.0 7.6 TC = +25°C Min 2.3 2.3 2.0 3.5 2.0 2.0 2.4 3.2 2.4 3.2 0.7 1.3 2.0 Max 4.8 5.6 5.5 8.0 6.0 5.0 5.6 8.5 6.0 7.6 TC = +85°C Min 2.3 2.3 2.0 3.5 2.0 2.0 2.4 3.2 2.4 3.2 0.7 1.3 2.0 Max 5.3 6.4 5.5 8.0 6.0 5.0 5.6 8.5 6.0 7.6 Units ns ns ns ns ns ns ns ns ns Conditions Figures 1, 2 Figures 1, 2 Figure 3 Figure 3 Figure 4 Figure 4 Figures 1, 2 Figures 1, 2 Figures 1Figure 2 Test Circuit Switch Positions for Parameter Testing Parameter tPLH, tPHL tPHZ, tPZH tPLZ, tPZL S-Position Open Open Open FIGURE 1.
