74ALVCH16373 Datasheet – 16-bit D-type Transparent Latch

Part Number : 74ALVCH16373

Function : 2.5 V / 3.3 V 16-bit D-type transparent latch (3-State)

Package : 48 Pin SSOP, TSSOP Type

Manufacturers : Philips Electronics

Logic Symbol :

74ALVCH16373 datasheet

 

Description

The 74ALVCH16373 is 16-bit D-type transparent latch featuring separate D-type inputs for each latch and 3-state outputs for bus oriented applications. Incorporates bus hold data inputs which eliminate the need for external pull-up or pull-down resistors to hold unused inputs.
One latch enable (LE) input and one output enable (OE) are provided per 8-bit section. The 74ALVCH16373 consists of 2 sections of eight D-type transparent latches with 3-state true outputs. When LE is HIGH, data at the nDn inputs enter the latches. In this condition the latches are transparent, therefore a latch output will changeeach time its corresponding D-input changes. When LE is LOW, the latches store the information that was present at the nDn inputs at a set-up time preceding the LOW-to-HIGH transition of LE. When OEis LOW, the contents of the eight latches are available at the outputs. When OEis HIGH, the outputs go to the high-impedance OFF-state. Operation of the OEinput does not affect the state of the latches.

Features

1. Wide supply voltage range from 1.2 V to 3.6 V
2. Complies with JEDEC standard JESD8-B
3. CMOS low power consumption

General Description

The 74ALVCH16373 contains sixteen non-inverting latches with 3-STATE outputs and is intended for bus oriented applications. The device is byte controlled. The flip-flops appear to be transparent to the data when the Latch Enable (LE) is HIGH. When LE is LOW, the data that meets the setup time is latched. Data appears on the bus when the Output Enable (OE) is LOW. When OEis HIGH, the outputs are in a high impedance state. The ALVCH16373 data inputs include active bushold circuitry, eliminating the need for external pull-up resistors to hold unused or floating data inputs at a valid logic level. The 74ALVCH16373 is designed for low voltage (1.65V to 3.6V) VCCapplications with output compatibility up to 3.6V. The 74ALVCH16373 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation.
