SN74HC42DR datasheet

Description

These decimal decoders consist of eight inverters and ten 4-input NAND gates. The inverters are connected in pairs to make BCD input data available for decoding by the NAND gates. Full decoding of valid input logic ensures that all inputs remain off for all invalid input conditions.

74LS07 Datasheet PDF – HEX Buffers / Drivers

Posted on by pinout

Part Number: 74LS07, 7407

Function: HEX BUFFER / DRIVERS WITH OPEN-COLLECTOR HIGH-VOLTAGE OUTPUTS

Package: DIP, SOIC, SSOP, SO 14 Pin Type

Manufacturer: Texas Instruments

Pinouts:
74LS07 pinout

Description

These hex buffers/drivers feature high-voltage open-collector outputs to interface with high-level circuits or for driving high-current loads. They are also characterized for use as buffers for driving TTL inputs.

The 74LS07 devices have a rated output voltage of 30 V, and the SN74LS17 has a rated output voltage of 15 V. The maximum sink current is 30 mA for the SN54LS07 and 40 mA for the SN74LS07 and SN74LS17.

Ordering Information:

74LS07 datasheet

Features

1. Convert TTL Voltage Levels to MOS Levels

2. High Sink-Current Capability

3. Input Clamping Diodes Simplify System Design

4. Open-Collector Driver for Indicator Lamps and Relays
