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.
