74F598
8-bit shift register with input storage registers (3-State)
2
1991 Oct 21
853–1583 04407
FEATURES
High impedance PNP base input for reduced loading (20
μ
A in
High and Low states)
8–bit 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 3–State I/O storage register inputs and shift register
parallel outputs
DESCRIPTION
The 74F598 consists of an 8–bit storage register feeding a
parallel–in/serial–in, parallel–out/serial–out 8–bit shift register. Both
the storage register and shift register have positive edge–triggered
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.
