8-bit addressable latch
Rev. 8 — 5 December 2022
Product data sheet
1. General description
The 74HC259; 74HCT259 is an 8-bit addressable latch. The device features four modes of
operation. In the addressable latch mode, data on the D input is written into the latch addressed
by the inputs A0 to A3. The addressed latch will follow the data input, non-addressed latches
will retain their previous states. In memory mode, all latches retain their previous states and are
unaffected by the data or address inputs. In the 3-to-8 decoding or demultiplexing mode, the
addressed output follows the D input and all other outputs are LOW. In the reset mode, all outputs
are forced LOW and unaffected by the data or address inputs. Inputs include clamp diodes. This
enables the use of current limiting resistors to interface inputs to voltages in excess of VCC
.

[1] Typical values are measured at nominal supply voltage (VCC = 3.3 V and VCC = 5.0 V).
[2] tpd is the same as tPLH and tPHL
[3] tt is the same as tTHL and tTLH
.
.
[4] CPD is used to determine the dynamic power dissipation (PD in μW).
PD = CPD × VCC 2 × fi × N + Σ(CL × VCC 2 × 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 × VCC 2 × fo) = sum of the outputs.
