1 ps2085e 09/14/99 product description pericom semiconductor?s pi74fct series of logic circuits are produced using the company?s advanced 0.6 micron cmos technology, achieving industry leading speed grades. all pi74fct2xxx devices have a built-in 25 ohm series resistor on all outputs to reduce noise due to reflections, thus eliminating the need for an external terminating resistor. the pi74fct193 is a high-speed cmos 4-bit binary up/down counter. it has a single clock with clock enable and up/down control inputs and ripple carry output. the 193 has asynchronous preload inputs which override the count inputs. all inputs have clamp diodes for undershoot noise suppression. all outputs have ground bounce suppression. logic block diagram product features pi74fct193/2193t is pin compatible with bipolar fast? series at a higher speed and lower power consumption 25 w series resistor on all outputs (fct2xxx only) ttl input and output levels low ground bounce outputs (25 w series only) extremely low static power hysteresis on all inputs industrial operating temperature range: ?40c to +85c packages available: ? 16-pin 150 mil wide plastic qsop (q) ? 16-pin 300 mil wide plastic soic (s) q 0 -q 3 tcu 25 w (fct2xxx only) 25 w (fct2xxx only) 25 w (fct2xxx only) =f =0 4-bit register q+cup-cdn cup cdn cpu cpd d 0 -d 3 pl mr tcd 1234567890123456789012345678901212345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901 212345678901 1 2345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012 1234567890 1 1234567890123456789012345678901212345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901 212345678901 pi74fct193t (25 w w w w w series) pi74fct2193t high-speed cmos presettable synchronous 4-bit binary counters
