Low-Voltage 20-Bit D-Type Latch with 3.6-V Tolerant Inputs and Outputs
D-type latch. Designed for use in 1.8-V, 2.5-V or 3.3-V systems, it
achieves high-speed operation while maintaining the CMOS low
power dissipation.
up to 3.6 V.
20-bit latch. The 20 latches are transparent D-type latches. The
device has noninverting data (D) inputs and provides true data at
its outputs. While the latch-enable (1LE or 2LE) input is high,
the Q outputs of the corresponding 10-bit latch follow the D
inputs. When LE is taken low, the Q outputs are latched at the
levels set up at the D inputs. When the OE input is high, the outputs are in a high-impedance state. This device is
designed to be used with 3-state memory address drivers, etc.
Features
The TC74VCX16841FT is a high-performance CMOS 20-bit
It is also designed with overvoltage tolerant inputs and outputs
The TC74VCX16841FT can be used as two 10-bit latches or one
All inputs are equipped with protection circuits against static discharge.
