3.3V CMOS PRESETTABLE  
IDT74LVC163A  
SYNCHRONOUS 4-BIT BINARY  
COUNTER WITH SYNCHRONOUS  
RESET, 5 VOLT TOLERANT I/O  
FEATURES:  
Outputs (Q0 to Q3) may be preset to a high or low level. A low level at the  
parallelenableinput(PE)disablesthecountingactionandcausesthedata  
atthedatainputs(D0 toD3)tobeloadedintothecounteronthepositive-going  
edge of the clock (provided that the set-up and hold time requirements for  
PE are met). Preset takes place regardless of the levels at count enable  
inputs (CEP and CET). A low level at the master reset input (MR) sets all  
fouroutputsoftheflip-flops(Q0 toQ3)tolowlevelafterthenextpositive-going  
transition on the clock (CP) input (provided that the set-up and hold time  
requirements for PE are met).  
• 0.5 MICRON CMOS Technology  
• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using  
machine model (C = 200pF, R = 0)  
• VCC = 3.3V ± 0.3V, Normal Range  
• VCC = 2.7V to 3.6V, Extended Range  
• CMOS power levels (0.4µ W typ. static)  
• Rail-to-Rail output swing for increased noise margin  
• All inputs, outputs, and I/Os are 5V tolerant  
• Supports hot insertion  
This action occurs regardless of the levels of CP, PE, CET, and CEP  
inputs. This synchronous reset feature enables the designer to modify the  
maximum count with only one external NAND gate.  
• Available in TSSOP package  
DRIVE FEATURES:  
• High Output Drivers: ±24mA  
• Reduced system switching noise  
The look-ahead carry simplifies serial cascading of the counters. Both  
count enable inputs (CEP and CET) must be high to count. The CET input  
is fed forward to enable the terminal count output (TC). The TC output thus  
enabled will produce a high output pulse of a duration approximately equal  
to a high level output of Q0. This pulse can be used to enable the next  
cascaded stage. The maximum clock frequency for the cascaded counters  
is determined by the CP to TC propagation delay and CEP to CP set-up  
time, according to the following formula:  
APPLICATIONS:  
• 5V and 3.3V mixed voltage systems  
• Data communication and telecommunication systems  
DESCRIPTION:  
The LVC163A is a synchronous presettable binary counter, which  
features an internal look-ahead carry and can be used for high-speed  
counting. Synchronous operation is provided by having all the flip-flops  
clocked simultaniously on the positive-going edge of the clock (CP).
