HCF4042M013TR

Latches Overview

The HCF4042M013TR is a monolithic integrated circuit containing four clocked D latch circuits, fabricated in Metal Oxide Semiconductor technology. It features complementary buffered outputs (Q and Q) for each latch, with data transfer controlled by a common clock input and a polarity selection pin. The device operates within a supply voltage range of 3V to 20V and supports an operating temperature from -55°C to +125°C. Propagation delays vary based on voltage; at 15V, typical DATA-to-Q delay is 80ns and CLOCK-to-Q is 160ns. Input leakage current is specified at ±1µA maximum at 18V.

Latches Feature Summary

• Contains four independent latch circuits sharing a single common clock input.
• Provides complementary buffered outputs for each latch stage.
• Features programmable clock polarity to define active data transfer levels.
• Offers standardized symmetrical output characteristics with balanced impedance.

Latches Applications

• Clock polarity control logic
• Data storage and buffering in digital systems
• Low power TTL compatible interface circuits

Latches Procurement Notes

Verify the specific ordering suffix M013TR corresponds to the tape and reel packaging format required for automated assembly. Confirm that the component meets RoHS3 compliance standards as indicated by the manufacturer's documentation. Ensure design compatibility with the specified SOP-16 package dimensions and thermal dissipation limits during procurement planning.

Latches Selection Notes

Select this component when designing circuits requiring multiple latches synchronized by a shared clock signal. The availability of both Q and Q outputs simplifies differential signaling requirements. Consider the propagation delay specifications relative to the target operating voltage to ensure timing margins are met within the system architecture.

Latches FAQ

How does the POLARITY input affect data transfer?

When POLARITY is low, data transfers to the outputs during the low level of the clock. When POLARITY is high, data transfers during the high level of the clock.

What is the maximum input leakage current?

The maximum input leakage current is specified as ±1µA at VDD = 18V and TA = 25°C.
