description/ordering information

The ’HC373 devices are octal transparent D-type

latches designed for 2-V to 6-V VCC operation.

When the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is low, the Q outputs

are latched at the logic levels of the D inputs.

A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high

or low) or the high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines

1TDA7388

4 x 45 W quad bridge car radio amplifier

Datasheet − production data

Features

■High output power capability:

–4 x 45 W / 4 Ω max.–4 x 26 W / 4 Ω @ 14.4 V, 1 kHz, 10 %

■Low distortion

■Low output noise

■Standby function

■Mute function

■Automute at min. supply voltage detection

■Low external component count:

–Internally fixed gain (26 dB)–No external compensation–No bootstrap capacitors

Protections:

■Output short circuit to gnd, to VS, across the load

■Very inductive loads

■Overrating chip temperature with soft thermal limiter

■Load dump voltage

■Fortuitous open GND

■Reversed battery

■ESDDescription

The TDA7388 is an AB class audio power amplifier, packaged in Flexiwatt 25 and designed for high end car radio applications.

Based on a fully complementary PNP/NPN configuration, the TDA7388 allows a rail to rail output voltage swing with no need of bootstrap capacitors. The extremely reduced boundary components count allows very compact sets.
