SN74167

The SN74167 monolithic,fully synchronous programmable counters utilize series 74 TTL circuitry to achieve 32-megahertz typical maximum operatting frequencles.These decade counter feature buffered clock,clear,enable and set-to-nine inputs to control the operation of the counter,and a strobe input to enable or inhibit the rate input/decoding AND-OR-INVERT gates.The outputs have additional gating for cascading and transferring unity-count rates.

Features of the SN74167 are:(1)perform fixed-rate or variable-rate frequency division ; (2)for applications in arlthmetlc ,radar, digital-to-analog(D/A),analog-to-digital(A/D),and other conversion operations; (3)typical maximum clocl frequency:32MHz.

The absolute maximum ratings of the SN74167 can be summarized as:(1)supply voltage,VCC:7V; (2)input voltage:5.5V; (3)operating free-air temperature range:0 to70; (4)storage temperature range:-65 to 150.

The electrical characteristics(Ta=25) of the SN74167 can be summarized as:(1)VIH:2V MIN; (2)VIL:0.8V MAX; (3)VI:-1.5V MAX;(4)VOL:0.2V TYP 0.4V MAX; (5)ICCH:43mA TYP;(6)ICCL:65mA TYP 99mA MAX.If you want to know more information such as the electrical characteristics of SN74167 ,please download the datasheet in www.seekdatasheet.com .
