•
•
•
•
•
•
Buffered inputs and outputs
Four operating modes
Typical propagation delay of 15ns at VCC = 5V, CL
= 15pF, TA = 25oC
Fanout (over temperature range)
– Standard Outputs: 10 LSTTL loads
– Bus driver outputs: 15 LSTTL loads
Wide operating temperature range: -55oC to 125oC
Balanced propagation delay and transition times
Significant power reduction compared to LSTTL
logic ICs
HC types
– 2 V to 6 V operation
– High noise immunity: NIL = 30%, NIH = 30% of
VCC at VCC = 5 V
HCT types
– 4.5 V to 5.5 V operation
– Direct LSTTL input logic compatability, VIL = 0.8
V (max), VIH = 2 V (min)
– CMOS input compatibility, II ≤ 1µA at VOL, VOH

6 Parameter Measurement Information
Phase relationships between waveforms were chosen arbitrarily. All input pulses are supplied by generators
having the following characteristics: PRR ≤ 1 MHz, ZO = 50 Ω, tt < 6 ns.
For clock inputs, fmax is measured when the input duty cycle is 50%.
The outputs are measured one at a time with one input transition per measurement.

7 Detailed Description
7.1 Overview
The CDx4HC(T)259 8-bit addressable latches are designed for general-purpose storage applications in
digital systems. Specific uses include working registers, serial-holding registers, and active-high decoders or
demultiplexers. They are multifunctional devices capable of storing single-line data in eight addressable latches
and being a 1-of-8 decoder or demultiplexer with active-high outputs.
Four distinct modes of operation are selectable by controlling the clear (CLR) and enable (G) inputs:
•
•
•
•
Addressable-latch mode: CLR = HIGH; G = LOW
– Data at the data-in terminal is written into the addressed latch
– The addressed latch follows the data input, with all unaddressed latches remaining in their previous states
Memory mode: CLR = HIGH; G = HIGH
– All latches remain in their previous states and are unaffected by the data or address inputs
– To eliminate the possibility of entering erroneous data in the latches, G should be held high (inactive) while
the address lines are changing
1-of-8 decoding or demultiplexing mode: CLR = LOW; G = LOW
– The addressed output follows the level of the D input with all other outputs low
Clear mode: CLR = LOW; G = HIGH
– All outputs are low and unaffected by the address and data inputs

8 Power Supply Recommendations
The power supply can be any voltage between the minimum and maximum supply voltage rating located in the
Recommended Operating Conditions. Each VCC terminal should have a good bypass capacitor to prevent power
disturbance. A 0.1-μF capacitor is recommended for this device. It is acceptable to parallel multiple bypass caps
to reject different frequencies of noise. The 0.1-μF and 1-μF capacitors are commonly used in parallel. The
bypass capacitor should be installed as close to the power terminal as possible for best results.
9 Layout
9.1 Layout Guidelines
When using multiple-input and multiple-channel logic devices inputs must not ever be left floating. In many
cases, functions or parts of functions of digital logic devices are unused; for example, when only two inputs of a
triple-input AND gate are used or only 3 of the 4 buffer gates are used. Such unused input pins must not be left
unconnected because the undefined voltages at the outside connections result in undefined operational states.
All unused inputs of digital logic devices must be connected to a logic high or logic low voltage, as defined by the
input voltage specifications, to prevent them from floating. The logic level that must be applied to any particular
unused input depends on the function of the device. Generally, the inputs are tied to GND or VCC, whichever
makes more sense for the logic function or is more convenient.

10.5 Electrostatic Discharge Caution
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled
with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric changes could cause the device not to meet its published
specifications.
