SN54284

The SN54284 high-speed TTL circuits are designed to be used in high-performance parallel multiplication applications.When connected as shown in Figure A,these circuits peraform the positive-logic multiplication of two 4-bit binary words.The eight-bit binary product is generated with typically only 40 nanoseconds delay.

Features of the SN54284 are:(1)fast multiplication of two binary numbers 8-bit product in 40 ns typical; (2)expandable for N-Bit-by-n-Bit applications:16-bit product in 70ns typical;32-bit product in 103ns typical; (3)fully compatible with most TTL circuits; (4)diode-clamped inputs simplify system design.

The absolute maximum ratings of the SN54284 can be summarized as:(1)supply voltage,VCC:7V; (2)input voltage:5.5V; (3)operating free-air temperature range:-55 to 125; (4)storage temperature range:-65 to 150.

The electrical characteristics(Ta=25) of the SN54284 can be summarized as:(1)VIH:2.0V MIN; (2)VIL:-1.5V MAX; (3)V1:40A MAX;(4)VOL:0.4V MAX; (5)ICC:92mA TYP 110mA MAX.If you want to know more information such as the electrical characteristics ,please download the datasheet in www.seekdatasheet.com .
