SN74LV393A
SN74LV393A is Dual 4-Bit Binary Counters manufactured by Texas Instruments.
Features
- VCC operation of 2 V to 5.5 V
- Max tpd of 10 ns at 5 V
- Typical VOLP (Output Ground Bounce) <0.8 V at
VCC = 3.3 V, TA = 25°C
- Typical VOHV (Output VOH Undershoot) > 2.3 V at
VCC = 3.3 V, TA = 25°C
- Ioff supports Partial-Power-Down-Mode operation
- Dual 4-bit binary counters with individual clocks
- Direct clear for each 4-bit counter
- Can significantly improve system densities by reducing counter package count by 50 percent
- Latch-Up performance exceeds 100 m A per JESD
