1. General description
The 74HC393; HCT393 is a high-speed Si-gate CMOS device and is pin compatible with
Low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard
no. 7A.
The 74HC393; 74HCT393 contains 4-bit binary ripple counters with separate clocks
(1CP and 2 CP) and master reset (1MR and 2MR) inputs to each counter.
The operation of each half of the 74HC393; 74HCT393 is the same as the 74HC93;
74HCT93, except no external clock connections are required.
The counters are triggered by a HIGH-to-LOW transition of the clock inputs.
The counter outputs are internally connected to provide clock inputs to succeeding
stages. The outputs of the ripple counter do not change synchronously and should not be
used for high-speed address decoding.
The master resets (1MR and 2MR) are active-HIGH asynchronous inputs to each 4-bit
counter. A HIGH level on the nMR input overrides the clock and sets the outputs LOW.
2. Features
■Two 4-bit binary counters with individual clocks
■Divide by any binary module up to 28 in one package
■Two master resets to clear each 4-bit counter individually

16. Data sheet status
[1] Please consult the most recently issued data sheet before initiating or completing a design.
[2] The product status of the device(s) described in this data sheet may have changed since this data sheet was published. The latest information is available on the Internet at
URL http://www.semiconductors.philips.com.
[3] For data sheets describing multiple type numbers, the highest-level product status determines the data sheet status.
17. Definitions
Short-form specification — The data in a short-form specification is
extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with
the Absolute Maximum Rating System (IEC 60134). Stress above one or
more of the limiting values may cause permanent damage to the device.
These are stress ratings only and operation of the device at these or at any
other conditions above those given in the Characteristics sections of the
specification is not implied. Exposure to limiting values for extended periods
may affect device reliability.
Application information — Applications that are described herein for any
of these products are for illustrative purposes only. Philips Semiconductors
make no representation or warranty that such applications will be suitable for
the specified use without further testing or modification.
