TC74VCX16841FT

TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

TC74VCX16841FT

Low-Voltage 20-Bit D-Type Latch with 3.6-V Tolerant Inputs and Outputs

The TC74VCX16841FT is a high-performance CMOS 20-bit

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.

It is also designed with overvoltage tolerant inputs and outputs

up to 3.6 V.

The TC74VCX16841FT can be used as two 10-bit latches or one

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

Weight: 0.25 g (typ.)

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.

All inputs are equipped with protection circuits against static discharge.
