HD74LV4040A 12-stage Binary Counter ADE-205-282 (Z) 1st Edition April 1999 Description The HD74LV4040A is a 12 stage counter. This device is incremented on the falling edge (negative transition) of the input clock, and all its output is reset to a low level by applying a logical high on its reset input. Low-voltage and high-speed operation is suitable for the battery-powered products (e.g., notebook computers), and the low-power consumption extends the battery life. Features • • • • • • VCC = 2.0 V to 5.5 V operation All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V) All outputs VO (Max.) = 5.5 V (@VCC = 0 V) Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typical VOH undershoot > 2.3 V (@VCC = 3.3 V, Ta = 25°C) Output current ±6 mA (@VCC = 3.0 V to 3.6 V), ±12 mA (@VCC = 4.5 V to 5.5 V) Function Table Inputs Output CLK CLR Qn ↑ L Remains unchanged ↓ L Changed X H All outputs low Note: H: L: X: ↑: ↓: High level Low level Immaterial Low to high transition High to low transition HD74LV4040A Pin Arrangement Q12 1 16 VCC Q6 2 15 Q11 Q5 3 14 Q10 Q7 4 13 Q8 Q4 5 12 Q9 Q3 6 11 CLR Q2 7 10 CLK 9 Q1 GND 8 (Top view) 2 HD74LV4040A Absolute Maximum Ratings Item Supply voltage range Input voltage range* 1 Output voltage range* 1, 2 Symbol Ratings Unit VCC –0.5 to 7.0 V VI –0.5 to 7.0 V VO –0.5 to VCC + 0.5 V –0.5 to 7.0 Conditions Output: H or L VCC: OFF Input clamp current I IK –20 mA VI < 0 Output clamp current I OK ±50 mA VO < 0 or VO > VCC Continuous output current IO ±25 mA VO = 0 to VCC Continuous current through VCC or GND I CC or IGND ±50 mA Maximum power dissipation at Ta = 25°C (in still air)*3 PT 785 mW 500 Storage temperature Tstg –65 to 150 SOP TSSOP °C Notes: The absolute maximum ratings are values which must not individually be exceeded, and furthermore, no two of which may be realized at the same time. 1. The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 2. This value is limited to 5.5 V maximum. 3. The maximum package power dissipation was calculated using a junction temperature of 150°C. 3 HD74LV4040A Recommended Operating Conditions Item Symbol Min Max Unit Supply voltage range VCC 2.0 5.5 V
