High speed: tPD = 20 ns (typ.) at VCC = 6 V
Low power dissipation:
ICC = 4 µA (max.) at TA = 25 °C
High noise immunity:
VNIH = VNIL = 28 % VCC (min.)
Symmetrical output impedance:
|IOH| = IOL = 4 mA (min)
Balanced propagation delays: tPLH ~= tPHL
Wide operating voltage range:
VCC (OPR) = 2 V to 6 V

held high (inactive) while the address lines are
changing. If ENABLE is held high and
CLEAR is taken low, all eight latches are
cleared to the low state. If ENABLE is low, all
latches except the addressed latch will be
cleared. The addressed latch will instead follow
the D input, effectively implementing a 3-to-8 line
decoder.
All inputs are equipped with protection circuits to
guard against static discharge and transient
excess voltage.

Description
The M74HC259 is a high-speed CMOS 8-bit
addressable latch manufactured with silicon gate
2
C MOS technology.
The M74HC259 has single data input (D) 8 latch
outputs (Q0-Q7), 3 address inputs (A, B, and C),
common enable input (E), and a common
CLEAR input. To operate this device as an
addressable latch, data is held on the D input,
and the address of the latch into which the data is
to be entered is held on the A, B, and C inputs.
When ENABLE is taken low, the data flows
through to the address outputs. The data is
stored on the positive-going edge of the
