74AHC594-Q100;
74AHCT594-Q100
8-bit shift register with output register
Rev. 4 — 7 July 2021
Product data sheet
1. General description
The 74AHC594-Q100; 74AHCT594-Q100 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. 7-A.
The 74AHC594-Q100; 74AHCT594-Q100 is an 8-bit, non-inverting, serial-in, parallel-out shift
register that feeds an 8-bit D-type storage register. Separate clocks (SHCP and STCP) and direct
overriding clears (SHR and STR) are provided on both the shift and storage registers. A serial
output (Q7S) is provided for cascading purposes.
Both the shift and storage register clocks are positive-edge triggered. If the user wishes to connect
both clocks together, the shift register will always be one count pulse ahead of the storage register.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100
(Grade 1) and is suitable for use in automotive applications.

Typical values are measured at nominal supply voltage (VCC = 3.3 V and VCC = 5.0 V).
CPD is used to determine the dynamic power dissipation (PD in μW).

PD = CPD x VCC x fi x N + Σ(CL x VCC x fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in V;
N = number of inputs switching;

Σ(CL x VCC x fo) = sum of the outputs.
