SN74284

The SN74284 high-speed TTL circuits are designed to be used in high-performance parallel multiplication applications.When connected as shown in figure A,these circuits perform 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 SN74284 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 103 ns typical; (3)fully compatible with most TTL circuits; (4)diode-clamped inputs simplify system design.

The absolute maximum ratings of the SN74284 can be summarized as:(1)supply voltage,VCC:7V; (2)input voltage:5.5V; (3)operating free-air temperature range:0 to 70; (4)storage temperature range:-65 to 150.

The electrical characteristics(Ta=25) of the SN74284 can be summarized as:(1)VIH:2V MIN; (2)VIL:0.8V MAX; (3)IOH:40A; (4)II:1mA; (5)IIH:40A; (6)IIL:-1mA.If you want to know more information such as the electrical characteristics ,please download the datasheet in www.seekdatasheet.com .
