74F598

8-bit shift register with input storage registers (3-State)

1991 Oct 21

8531583 04407

FEATURES

High impedance PNP base input for reduced loading (20

A in

High and Low states)

8bit parallel storage register

Shift register has asynchronous direct overriding reset

Shift load SHLD is functional when SHCP is Low and locked out

when SHCP is High.

Guaranteed shift frequency DC to 105MHz

Parallel 3State I/O storage register inputs and shift register

parallel outputs

DESCRIPTION

The 74F598 consists of an 8bit storage register feeding a

parallelin/serialin, parallelout/serialout 8bit shift register. Both

the storage register and shift register have positive edgetriggered

clocks. The shift register has asynchronous reset and when SHCP

is Low, it has asynchronous load.

The shift register load function has been modified to load when both

SHLD and SHCP are Low. When SHCP is High the shift register

load operation is not performed. Data will be properly shifted on the

rising edge of SHCP when SHLD is High.

Notes to function table
D0 D7 = The level of the steady state inputs to the serial multiplexer.
H = High voltage level
I0 I7 = The level of the steady state input at the respective I/O terminal is loaded into the flipflop while the flipflop outputs ( except Q7) are isolated

from the I/O terminal.

= Low voltage level

NC= No change
O0 O7 = The level of the respective Qn flipflop prior to the last clock LowtoHigh transition
X = Don't care
Z = High impedance "off" state
*

= When the OE input is High, all I/O terminals are at the High impedance state, sequential operation or cleaning of the register is not affected.

= LowtoHigh clock transition

= Not LowtoHigh clock transition

Notes to DC electrical characteristics
1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type.
2. All typical values are at V

= 5V, T

amb

= 25

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

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.
