New Fast, Low-Power Comparator Family From Texas Instruments Consumes Half the Power of Current Product Offerings

DALLAS (March 17, 1997) -- A new family of ultra-fast, low power precision comparators are now available from Texas Instruments (TI). These comparators, designed to interface directly to transistor-transistor logic (TTL), are ideal in applications such as hard disk drives and high-speed scanners.

The devices, designated the TL3016 and the TL3116, offer faster propagation delay times and lower power consumption than competitive solutions, at one-third the cost. The TL3016 and TL3116 operate from either a single 5V supply or dual +/-5V supplies, and feature very tight offset voltage and high gain for precision applications. The TL3116 has an input common mode range that extends below the negative supply rail, making it ideal for sensing signals near the negative supply.

Features/Benefits

Ultra-fast propagation delay 7ns Typ	Provides extremely fast operation for high-speed applications like hard disk drives and scanners.
Low supply current, 11mA	Extends battery life in battery-powered applications.
Single and split supply operation 5V and +/-5V	Gives a wide supply voltage range that encompasses several applications.
Complementary output to TTL	Interfaces directly to TTL logic.
Low input offset voltage 1.5mV Typ	Great for precision applications.
Output latch capability	Retains input data at the output. The outputs will remain latched as long as the latch pin is held high.
Available in SOIC and TSSOP packages	Allows low-profile packages for high density circuits.

End Equipment Applications

Hard disk drives
High-speed scanners
Medical imaging systems
High-speed analog-to-digital converters (ADCs)

Pricing, Packaging and Availability

The TL3016 and the TL3116 are now available from Texas Instruments and its authorized distributors. The devices are available in a small-outline integrated circuit (SOIC) and a thin shrink-small outline package (TSSOP). Pricing is $1.04 for TL3X16CD, $1.15 for TL3X16ID, $1.14 for TL3X16CPWLE and $1.25 for TL3X16IPWLE, all in quantities of 1,000.
