1. General Information

️· Device: Nexperia 74LV393
️· Function: Dual 4-bit binary ripple counter.
️· Manufacturer: Nexperia
️· Document Type: Product Data Sheet (Revision 6, dated 19 March 2021)

2. Electrical Characteristics (Key Highlights)

️· Supply Voltage (VCC): The datasheet specifies different voltage ranges for testing and measurements (less than 2.7V, 2.7V to 3.6V).
️· Input/Output Timing: Measurement points for VCC and input/output levels are defined. *tPHL, tPLH* is tested with tr, tf <= 2.5 ns.
️· Power Dissipation Capacitance (CPD): CPD = 23pF at VCC = 3.3V. A formula is provided to calculate dynamic power dissipation: `P D = C PD x V CC x f i x N + Σ(C L x V CC x f o )` (see datasheet for variables).
️· Test Data: Includes a table outlining the different parameters tested for the device under different conditions and load characteristics.

3. Timing Characteristics (Important Values)

️· *tPHL, tPLH*: These propagation delay values are critical for ripple counter operation, and are tested under specific conditions (specified input rise/fall times and load capacitances). The data sheet also makes the statement "t pd is the same as t PLH and t PHL ".
