SN54170J

The SN54170J is one of the SN54170 series.16-bit TTL register files incorporate the equivalent of 98 gates.The register file is organized as 4 words of 4 bits each and separate  on-chip decoding is provided for addressing the four word locations to either write-in or retrieve data.This permits simultaneous writing into one location and reading from another word location.

Features of the SN54170J are:(1)separate read/write addressing permits simultaneous reading and writing; (2)fast access times...typically 20 ns; (3)organized as 4 words of 4 bits; (4)expandable to 1024 words of n-bits; (5)for use as:scratch-pad memory;buffer storage between processors;bit storage in fast multiplication designs; (6)open-collector outputs with low .

The absolute maximum ratings of the SN54170J can be summarized as:(1)supply voltage,VCC:7V; (2)input voltage:5.5V; (3operating free-air temperature range:-55 to 125;(4)storage temperature range:-65 to 150.

The electrical characteristics(Ta=25) of the SN54170J can be summarized as:(1)VIH:2V MIN; (2)VIL:0.8V MAX; (3)VIK:-1.5V MAX;(4)VOL:0.2V TYP 0.4V MAX; (5)ICC:127mA TYP 140mA MAX.If you want to know more information such as the electrical characteristics of SN54170J ,please download the datasheet in www.seekdatasheet.com .
