N8277N

The N8277N is a kind of dual 8-bit shift register which provides the designer with 16 bits of serial storage at a typical shift rate of 20 MHz. It is available in plastic DIP package.

There are some features of N8277N as follows: (1)TRUE and COPLEMENT outputs are provided on each register's eighth bit; (2)positive edge triggering on clock input; (3)SEPERATE CLOCK lines (pins 7 and 10) for each 8-bit register are provided as well as a COMMON CLOCK line (pin 9) for all sixteen storage bits; (4)common RESET (pin 1); (5)AND-OR gating to the input of each 8-bit register is provided to accomplish the multiplex function; (6)direct replacement for 9328.

Then is about the DC electrical characteristics of N8277N: (1)VOH, output high voltage: 2.6 V min at VCC=4.75 V, IOH=-800A; (2)VOL, output low voltage: 0.4 V max at VCC=4.75 V, IOL=16 mA; (3)IOH, input high current: 40A max at pins Data, Reset, Clock seperate when VCC=5.25 V, VIN=4.5 V; 80A max at pins Data, Reset, Clock common when VCC=5.25 V, VIN=4.5 V; (4)IOL, input low current: -1.6 mA max at pins Data, Reset, Clock seperate when VCC=5.25 V, VIN=0.4 V; -3.2 mA max at pins Data, Reset, Clock common when VCC=5.25 V, VIN=0.4 V; (5)VBD, input breakdown voltage: 5.5 V min at VCC=4.75 V, IIN=10 mA; (6)ICC, supply current: 103 mA max at VCC=5.25 V.
