| LVITD Series LVC Low Voltage Logic 10-Tap Delay Modules Inputs accept voltages up to 5.5 V 74LVC type input can be driven from either 3.3V or 5V devices. This allows delay module to serve as a translator in a mixed 3.3V / 5V system environment. Operating Temp. -40OC to +85OC Low Profile 14-Pin Package Two Surface Mount Versions For 5-Tap 8-Pin Versions see LVMDM Series Electrical Specifications at 25OC LVC Logic 10 Tap P/N LVITD-12 LVITD-21 LVITD-30 LVITD-50 LVITD-60 LVITD-75 LVITD-80 LVITD-100 LVITD-125 LVITD-150 Tap Delay Tolerances +/- 5% or 2ns (>15ns +/- 1.0ns) Tap 1 Tap 2 Tap 3 Tap 4 Tap 5 Tap 6 Tap 7 Tap 8 Tap 9 Total - Tap 10 LVITD Schematic Vcc 14 Tap1 Tap3 Tap5 Tap7 Tap9 Tap10 13 12 11 10 9 8 1 IN 2 N/C 3 4 5 6 7 Tap2 Tap4 Tap6 Tap8 GND Tap-to-Tap (ns) 1.0 0.4 2.0 0.6 3.0 0.8 5.0 1.8 6.0 2.0 7.5 2.0 8.0 2.0 10.0 2.0 12.5 3.0 15.0 3.0 3 3 3 5 6 7.5 8 10 12.5 15 4 5 6 10 12 15 16 20 25 30 5 7 9 15 18 22.5 24 30 37.5 45 6 9 12 20 24 30 32 40 50 60 7 11 15 25 30 37.5 40 50 62.5 75 8 13 18 30 36 45 48 60 75 90 9 15 21 35 42 52.5 56 70 87.5 105 10 17 24 40 48 60 64 80 100 120 11 19 27 45 54 67.5 72 90 112.5 135 12 2.5 21 2.5 30 2.5 50 2.5 60 3.0 75 3.75 80 4.0 100 5.0 125 6.25 150 7.5 TEST CONDITIONS -- Low Voltage CMOS, LVC VCC Supply Voltage ................................................ 3.30VDC Input Pulse Voltage ................................................... 2.70V Input Pulse Rise Time ....................................... 3.0 ns max.
