74AHC594; 74AHCT594
8-bit shift register with output register
Rev. 02 — 9 June 2008
Product data sheet
1. General description
The 74AHC594; 74AHCT594 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; 74AHCT594 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.

For SO16 packages: above 70 °C the value of Ptot derates linearly at 8 mW/K.
For (T)SSOP16 packages: above 60 °C the value of Ptot derates linearly at 5.5 mW/K.
For DHVQFN16 packages: above 60 °C the value of Ptot derates linearly at 4.5 mW/K.

Typical values are measured at nominal supply voltage (VCC = 3.3 V and VCC = 5.0 V).
[2]
CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × 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 × VCC2 × fo) = sum of the outputs.
