8-Bit Addressable
Latch/1-of-8 Decoder
CMOS Logic Level Shifter
with LSTTL–Compatible Inputs
The MC74VHC259 is an 8–bit Addressable Latch fabricated with
silicon gate CMOS technology. It achieves high speed operation similar to
equivalent Bipolar Schottky TTL while maintaining CMOS low power
dissipation.
The internal circuit is composed of three stages, including a buffer
output which provides high noise immunity and stable output.
The VHC259 is designed for general purpose storage applications in
digital systems. The device has four modes of operation as shown in the
mode selection table.. In the addressable latch mode, the data on Data In
is written into the addressed latch. The addressed latch follows the data
input with all non–addressed latches remaining in their previous states. In
the memory mode, all latches remain in their previous state and are
unaffected by the Data or Address inputs. In the one–of–eight decoding
or demultiplexing mode, the addressed output follows the state of Data In
with all other outputs in the LOW state. In the Reset mode, all outputs are
LOW and unaffected by the address and data inputs. When operating the
VHC259 as an addressable latch, changing more than one bit of the
address could impose a transient wrong address. Therefore, this should
only be done while in the memory mode.
The MC74VHC259 input structure provides protection when volatges
up to 7 V are applied, regardless of the supply voltage. This allows the
MC74VHC259 to be used to interface 5 V circuits to 3 V circuits.
High Speed: tPD = 7.6 ns (Typ) at VCC = 5 V
Low Power Dissipation: ICC = 2 A (Max) at TA = 25°C
High Noise Immunity: VNIH = VNIL = 28% VCC
CMOS–Compatible Outputs: VOH > 0.8 VCC; VOL < 0.1 VCC @Load
Power Down Protection Provided on Inputs and Outputs
Balanced Propagation Delays
Pin and Function Compatible with Other Standard Logic Families
Latchup Performance Exceeds 300 mA
ESD Performance: HBM > 2000 V
