TP3155N Datasheet | National Semiconductor

Description The TP3155 is a monolithic CMOS logic circuit designed to generate transmit and receive frame synchronization pulses for up to 8 BOTM CODEC Filters Each frame sync pulse may be independently assigned to a time slot in a frame of up to 32 time slots Assignments are controlled by loading in an 8-bit word via a simple serial interface port This control interface is patible with that used on the TP3020 TP3021 and 2910 2911 CODECs enabling an easy upgrade to BO CODEC Filters to be made Features Y Y Y Y Y Controls up to 8 BO CODEC Filters Independent transmit and receive time slot assignments 8-channel unidirectional mode Up to 32 time slots per frame Serial control interface patible with TP3020 TP3021 CODECs LS TTL and CMOS patible inputs 5 m W 5V operation Typical Application TL H 5118 - 1 TRI-STATE is a registered trademarks of National Semiconductor Corp BOTM is a trademark of National Semiconductor Corp C1995 National Semiconductor Corporation TL H 5118 RRD-B30M115 Printed in U S A Absolute Maximum Ratings If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications VCC Relative to GND Voltage at Any Input or Output 7V VCC a 0 3V to GND b0 3V Operating Temperature Range (Ambient) Storage Temperature Range (Ambient) Maximum Lead Temperature (Soldering 10 seconds) ESD rating to be determined b 25 C to a 125 C b 65 C to a 150 C 300 C DC Electrical Characteristics Unless otherwise noted limits printed in BOLD characters are guaranteed for VCC e 5 0V g 5% TA e 0 C to a 70 C by correlation with 100% electrical testing at TA e 25 C All other limits are assured by correlation with other production tests and or product design and characterization Typicals specified at VCC e 5 0V TA e 25 C Parameter Input Voltage Levels VIH Logic High VIL Logic Low Input Currents All Inputs Except MODE MODE Output Voltage Levels VOH Logic High VOL Logic Low Power...
