74LVC161
Presettable synchronous 4-bit binary counter; asynchronous
reset
Rev. 6 — 30 September 2013
Product data sheet
1. General description
The 74LVC161 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 flip-flops clocked simultaneously on the positive-going edge of the
clock (pin CP). The outputs (pins Q0 to Q3) of the counters may be preset to a HIGH-level
or LOW-level. A LOW-level at the parallel enable input (pin PE) disables the counting
action and causes the data at the data inputs (pins D0 to D3) to be loaded into the counter
on the positive-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 (pins CEP and CET). A LOW-level at the master reset input (pin MR) sets all four
outputs of the flip-flops (pins Q0 to Q3) to LOW-level regardless of the levels at input pins
CP, PE, CET and CEP (thus providing an asynchronous clear function).
The look-ahead carry simplifies serial cascading of the counters. Both count enable inputs
(pin CEP and CET) must be HIGH to count. The CET input is fed forward to enable the
terminal count output (pin 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 tPHL
(propagation delay CP to TC) and tsu (set-up time CEP to CP) according to the formula:
1
f max = ----------------------------------t PHL max + t su
It is a high-performance, low-power, low-voltage, Si-gate CMOS device and superior to
most advanced CMOS compatible TTL families.

CPD is used to determine the dynamic power dissipation (PD in W).
PD = CPD VCC2 fi N + (CL VCC2 fo) where:
fi = input frequency in MHz; fo = output frequency in MHz
CL = output load capacitance in pF
VCC = supply voltage in V
N = number of inputs switching
(CL VCC2 fo) = sum of outputs
