Binary up/down counter74HC/HCT4516
FEATURES
• Output capability: standard
• ICC category: MSI
parallel load input (PL), four parallel inputs (D0 to D3), four
parallel outputs (Q0 to Q3), an active LOW terminal count
output (TC), and an overriding asynchronous master reset
input (MR).
Information on D0 to D3 is loaded into the counter while PL
GENERAL DESCRIPTION
The 74HC/HCT4516 are high-speed Si-gate CMOS
devices and are pin compatible with the “4516” of the
“4000B” series. They are specified in compliance with
JEDEC standard no. 7A.
The 74HC/HCT4516 are edge-triggered synchronous
up/down 4-bit binary counters with a clock input (CP), an
up/down count control input (UP/
DN), an active LOW
is HIGH, independent of all other input conditions except
the MR input, which must be LOW. When PL and CE are
LOW, the counter changes on the LOW-to-HIGH transition
of CP. UP/DN determines the direction of the count, HIGH
for counting up, LOW for counting down. When counting
up, TC is LOW when Q0 to Q3 are HIGH and CE is LOW.
When counting down, TC is LOW when Q0 to Q3 and CE
are LOW. A HIGH on MR resets the counter (Q0 to
Q3= LOW) independent of all other input conditions.
count enable input (CE), an asynchronous active HIGH
Logic equation for terminal count:
TC = CE .{(UP/DN).Q0.Q1.Q2.Q3+(UP DN⁄).Q0.Q1.Q2.Q3}

APPLICATION INFORMATION
Terminal count (TC) lines at the 2nd, 3rd, etc. Stages may have a negative-going glitch pulse resulting from differential
delays of different 4516s. These negative-going glitches do not affect proper 4516 operation. However, if the terminal
count signals are used to trigger other edge-sensitive logic devices, such as flip-flops or counters, the terminal count
signals should be gated with the clock signal using a 2-input OR gate such as HC/HCT32.
