74HC75N,652

Latches Overview

The 74HC75N,652 is a high-speed Si-gate CMOS quad bistable transparent latch from the NXP HC series. It features four latches controlled by two active HIGH enable inputs (LE12 and LE34). The device operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range of -40 °C to +125 °C. Propagation delay is typically 11 ns at 5.0 V with 15 pF load. Input capacitance is 3.5 pF, and power dissipation capacitance per latch is 42 pF. It is housed in a 16-lead DIP package.

Latches Feature Summary

• Provides four bistable latches with complementary Q and Q outputs for data storage.
• Features center pins for VCC and GND connections to simplify PCB layout.
• Includes ESD protection exceeding 2000 V under HBM and 200 V under MM standards.
• Operates across extended industrial temperature ranges up to +125 °C.

Latches Applications

• Data buffering in digital logic circuits
• Temporary storage of parallel data streams
• Interface between microprocessors and peripheral devices

Latches Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74HC75 family offers multiple options including SO, SSOP, and TSSOP. Confirm the temperature grade corresponds to your operational environment requirements. Check current product status on official manufacturer channels to ensure availability and compliance with latest JEDEC standards before finalizing procurement.

Latches Selection Notes

Select this component when transparent latch functionality with complementary outputs is required. Ensure the operating voltage aligns with the 2.0 V to 6.0 V specification. Consider the propagation delay characteristics relative to system clock speeds. Verify that the DIP package dimensions fit the mechanical constraints of the target assembly.

Latches Part Context

This part belongs to the 74HC75 family of quad bistable transparent latches manufactured by NXP Semiconductors. It is pin-compatible with low-power Schottky TTL (LSTTL) devices, facilitating direct replacement in legacy designs. The HC series utilizes high-speed silicon-gate CMOS technology, offering improved performance over older logic families while maintaining low power consumption.

Latches Replacement Considerations

Direct replacements include other manufacturers' 74HC75 variants that meet JEDEC standard no. 7A specifications. Ensure any substitute maintains the same 16-pin DIP footprint and electrical characteristics, particularly the supply voltage range and propagation delays, to guarantee functional compatibility.
