TC74HC590AP/AF
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74HC590AP,TC74HC590AF
8-Bit Binary Counter/Register with 3-State Outputs
The TC74HC590A is a high speed CMOS 8-BIT
COUNTER/REGISTER fabricated with silicon gate C2MOS
technology.
It achieves the high speed operation similar to epuivalent
LSTTL while maintaining the CMOS low power dissipation.
The internal counter counts on the positive going edge of
Counter Clock (CCK) when Counter Clock Enable ( CCKEN ) is
low. When Counter Clear ( CCLR ) is low, the internal counter is
cleared asynchronously to the clock.
Data in the internal counter are loaded into the register at
www.DataSphoeseitti4veUg.ocionmg edge of Register Clock (RCK), and the register
outputs are controlled by enable input ( G ).
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Features
• High speed: fmax = 62 MHz (typ.) at VCC = 5 V
• Low power dissipation: ICC = 4 μA (max) at Ta = 25°C
• High noise immunity: VNIH = VNIL = 28% VCC (min)
• Output drive capability: 15 LSTTL loads for QA to QH
10 LSTTL loads for RCO
• Symmetrical output impedance: |IOH| = IOL = 6 mA (min)
For QA to QH
|IOH| = IOL = 4 mA (min)
For RCO
• Balanced propagation delays: tpLH ∼− tpHL
• Wide operating voltage range: VCC (opr) = 2 to 6 V
• Pin and function compatible with 74LS590

Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or
www.DataSheet4U.coemven destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
Note 2: 500 mW in the range of Ta = −40 to 65°C. From Ta = 65 to 85°C a derating factor of −10 mW/°C shall be
applied until 300 mW.
