Important notice
Dear Customer,
On 7 February 2017 the former NXP Standard Product business became a new company with the
tradename
Nexperia.
Nexperia is an industry leading supplier of Discrete, Logic and PowerMOS
semiconductors with its focus on the automotive, industrial, computing, consumer and wearable
application markets
In data sheets and application notes which still contain NXP or Philips Semiconductors references, use
the references to Nexperia, as shown below.
Instead of http://www.nxp.com, http://www.philips.com/ or http://www.semiconductors.philips.com/,
use
http://www.nexperia.com
Instead of sales.addresses@www.nxp.com or sales.addresses@www.semiconductors.philips.com, use

74HC4040; 74HCT4040
12-stage binary ripple counter
Rev. 5 — 3 February 2016
Product data sheet
1. General description
The 74HC4040; 74HCT4040 is a 12-stage binary ripple counter with a clock input (CP),
an overriding asynchronous master reset input (MR) and twelve parallel outputs (Q0 to
Q11). The counter advances on the HIGH-to-LOW transition of CP. A HIGH on MR clears
all counter stages and forces all outputs LOW, independent of the state of CP. Each
counter stage is a static toggle flip-flop. Inputs include clamp diodes that enable the use of
current limiting resistors to interface inputs to voltages in excess of V
CC
.
2. Features and benefits

6. Pinning information
6.1 Pinning
(1) This is not a supply pin. The substrate is attached to this
pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However, if it is soldered, the solder land should remain
floating or be connected to GND.
