HD74LV393A Dual 4-bit Binary Counters ADE-205-276 (Z) 1st Edition April 1999 Description The HD74LV393A contain two 4-bit ripple carry binary counters, which can be cascaded to create a single divide-by-256 counter. The HD74LV393A is incremented on the high to low transition (negative edge) of the clock input, and each has an independent clear input. When clear is set high all four bits of each counter are set to a low level. This enables count trucation and allows the implementation of divide-by-N counter configurations. 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 = 25C) Typical VOH undershoot > 2.3 V (@VCC = 3.3 V, Ta = 25C) Output current 6 mA (@VCC = 3.0 V to 3.6 V), 12 mA (@VCC = 4.5 V to 5.5 V) HD74LV393A Function Table Inputs CLK X H L Note: H: L: X: : : High level Low level Immaterial Low to high transition High to low transition CLR H L L L L Output L No change No change No change Count up Pin Arrangement 1CLK 1 1CLR 2 1QA 3 1QB 4 1QC 5 1QD 6 GND 7 14 VCC 13 2CLK 12 2CLR 11 2QA 10 2QB 9 2QC 8 2QD (Top view) 2 HD74LV393A Absolute Maximum Ratings Item Supply voltage range Input voltage range* 1 1, 2 Symbol VCC VI VO Ratings -0.5 to 7.0 -0.5 to 7.0 -0.5 to VCC + 0.5 -0.5 to 7.0 Unit V V V Conditions Output voltage range* Output: H or L VCC: OFF Input clamp current Output clamp current Continuous output current Continuous current through VCC or GND Maximum power dissipation at Ta = 25C (in still air)*3 I IK I OK IO I CC or IGND PT -20 50 25 70 785 500 mA mA mA mA mW VI < 0 VO < 0 or VO > VCC VO = 0 to VCC SOP TSSOP Storage temperature Tstg -65 to 150 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 150C. 3 HD74LV393A Recommended Operating Conditions Item Supply voltage range Input voltage range Output voltage range Output current Symbol VCC VI VO I OH Min 2.0 0 0 -- -- -- -- I OL -- -- -- -- Input transition rise or fall rate t /v 0 0 0 Operating free-air temperature Ta -40 Max 5.5 5.5 VCC -50 -2 -6 -12 50 2 6 12 200 100 20 85 C ns/V A mA Unit V V V A mA H or L VCC = 2.0 V VCC = 2.3 to 2.7 V VCC = 3.0 to 3.6 V VCC = 4.5 to 5.5 V VCC = 2.0 V VCC = 2.3 to 2.7 V VCC = 3.0 to 3.6 V VCC = 4.5 to 5.5 V VCC = 2.3 to 2.7 V VCC = 3.0 to 3.6 V VCC = 4.5 to 5.5 V Conditions Note: Unused or floating inputs must be held high or low.
