74F373 Octal transparent latch (3-State)
74F374 Octal D-type flip-flop (3-State)
The 74F374 is an 8-bit edge triggered register coupled to eight
3-State output buffers. The two sections of the device are controlled
independently by clock (CP) and output enable (OE) control gates.
FEATURES
• 8-bit transparent latch — 74F373
• 8-bit positive edge triggered register — 74F374
• 3-State outputs glitch free during power-up and power-down
• Common 3-State output register
The register is fully edge triggered. The state of the D input, one
set-up time before the LOW-to-HIGH clock transition is transferred
to the corresponding flip-flop’s Q output.
The 3-State output buffers are designed to drive heavily loaded
3-State buses, MOS memories, or MOS microprocessors.
• Independent register and 3-State buffer operation
• SSOP Type II Package
The active-LOW output enable (OE) controls all eight 3-State buffers
independent of the register operation. When OE is LOW, the data in
the register appears at the outputs. When OE is HIGH, the outputs
are in high impedance “off” state, which means they will neither drive
nor load the bus.
DESCRIPTION
The 74F373 is an octal transparent latch coupled to eight 3-State
output devices. The two sections of the device are controlled
independently by enable (E) and output enable (OE) control gates.

TYPE
The data on the D inputs is transferred to the latch outputs when the
enable (E) input is HIGH. The latch remains transparent to the data
input while E is HIGH, and stores the data that is present one set-up
time before the HIGH-to-LOW enable transition.

3. Not more than one output should be shorted at a time. For testing I , the use of high-speed test apparatus and/or sample-and-hold
OS
techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting
of a high output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any
sequence of parameter tests, I tests should be performed last.

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.
Limitingvaluesdefinition— 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.
Disclaimers
Life support — These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be
expected to result in personal injury. Philips Semiconductors customers using or selling these products for use in such applications do so at their own risk and agree
to fully indemnify Philips Semiconductors for any damages resulting from such application.
Right to make changes — Philips Semiconductors reserves the right to make changes in the products—including circuits, standard cells, and/or software—described
or contained herein in order to improve design and/or performance. When the product is in full production (status ‘Production’), relevant changes will be communicated
viaaCustomerProduct/ProcessChangeNotification(CPCN).PhilipsSemiconductorsassumesnoresponsibilityorliabilityfortheuseofanyoftheseproducts,conveys
