ICL7665 Dual Comparator From an 8 page INTERSIL datasheet: Pins : 1 : OUT1 = Open Drain of N Channel MOSFET to Gnd. 2 : HYST1 = Open Drain of P Channel MOSFET to V+. 3 : SET1 = inv. Input of Comparator1 4 : Gnd 5 : HYST2 = Open Drain of P Channel MOSFET to V+. 6 : SET2 = inv. Input of Comparator2. 7 : OUT2 = Open Drain of N Channel MOSFET to Gnd. 8 : V+ From the Output of Comparator1 directly to the Gate of the HYST1 MOSFET and inverted to the Gate of the OUT1 MOSFET. From the Output of Comparator2 directly to the Gate of the OUT2 MOSFET and inverted to the Gate of the HYST2 MOSFET. Function of HYST1: Shorting an external resistor between Hyst1 and V+ lifts the undervoltage threeshold ( R from HYST1 to SET1, and R from SET1 to Gnd) Function of HYST2: Shorting an external resistor between Hyst2 and V+ lifts the overvoltage threeshold ( R from HYST2 to SET2 , and R from SET2 to Gnd) The noninverted Input of Comparator1 and 2 is connected to an 1.3 V reference. Absolute Maximum Ratings: Supply Voltage -0.3 to 18 V All inputs and outputs between (Gnd-0.3V) and (V+ + 0.3V) All Output Currents: | Imax | = 25 mA Pd = 200 mW _________________________________

ICL7673 Battery Back-up Switch
Von einem 8-seitigen INTERSIL Datenblatt:
Pins:
1 = Vo
2 = Vs = z.B. Batterie
3 = Sbar
4 = GND
5 = not connected
6 = Pbar
7 = n.c.
8 = Vp = Haupt- Stromversorgung
Vp und Vs werden verglichen. Die jeweils höhere Spannung wird
über P-Kanal- MOSFETs mit dem Ausgang Vo verbunden. Ist Vp
größer, wird der Ausgang Pbar über einen NMOS open Drain-
Ausgang nach Masse gezogen. Ist Vs größer, zieht stattdessen
Sbar Strom.
Umschalten ab 50mV Spannungsdifferenz.
Grenzwerte:
Vp , Vs , Pbar , Sbar = -0.3 ... 18V
Ip at Vp=5V: max 38mA
Is at Vs=3V: max 30mA
I Pbar or I Sbar: continuous max 50mA, peak max 150mA
P tot = 300mW
Characteristics:
Vp = Vs = 2.5 ... 15V
Quiescent Supply Current at Vp = 0V, Vs=3V:
typ 1.5uA, max 5 uA
Vp-Switch at I Load = 15mA: typ 8 Ohm, max 15 Ohm
Vs-Switch at I Load = 1mA, Vp=0V, Vs=3V:
typ 40 Ohm, max 100 Ohm
V Pbar or V Sbar Saturation Voltage at I sink = 3,2mA:
typ 150mV, max 400mV

permits an injection of a signal into the third decade counter.
TEST2: Input as test1 for the counter 5
TEST3: Input as test1 for the counter 7

Die Testeingänge sind nicht detailliert beschrieben. Sie sollen im
Normalbetrieb aber wohl an Vdd liegen.
Der eingebaute Oszillator dient nur zum Multiplexen der Anzeige. Als
Zeitbasis des Zählers dient ein zweites IC, hier ist ICM7207
vorgeschlagen.
