Octal D-type transparent latch; 3-state
FEATURES • ESD protection: HBM EIA/JESD22-A114-A exceeds 2000 V MM EIA/JESD22-A115-A exceeds 200 V. • Balanced propagation delays • All inputs have Schmitt-trigger actions • Common 3-state output enable input • Functionally identical to the 74AHC/AHCT563 and 74AHC/AHCT373 • Inputs accepts voltages higher than VCC • For AHC only: operates with CMOS input levels • For AHCT only: operates with TTL input levels • Specified from −40 to +85 °C and −40 to +125 °C. DESCRIPTION The 74AHC/AHCT573 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard No. 7A.
74AHC573; 74AHCT573
The 74AHC/AHCT573 are octal D-type transparent latches featuring separate D-type inputs for each latch and 3-state outputs for bus oriented applications. A Latch Enable (LE) input and an Output Enable (OE) input are common to all latches. The 74AHC/AHCT573 consists of eight D-type transparent latches with 3-state true outputs. When pin LE is HIGH, data at the Dn inputs enters the latches. In this condition the latches are transparent, i.e. a latch output will change state each time its corresponding D-input changes. When pin LE is LOW the latches store the information that was present at the D-inputs a set-up time preceding the HIGH-to-LOW transition of LE. When pin OE is LOW, the contents of the 8 latches are available at the outputs. When pin OE is HIGH, the outputs go to the high-impedance OFF-state. Operation of the OE input does not affect the state of the latches. The 74AHC/AHCT573 is functionally identical to the 74AHC/AHCT533, 74AHC/AHCT563 and 74AHC/AHCT373, but the 74AHC/AHCT533 and 74AHC/AHCT563 have inverted outputs and the 74AHC/AHCT563 and 74AHC/AHCT373 have a different pin arrangement.
QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf ≤ 3.0 ns. TYPICAL SYMBOL tPHL/tPLH CI CO CPD Notes 1. CPD is used to determine the dynamic power dissipation (PD in µW). PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in Volts; N = total load switching outputs; Σ(CL × VCC2 × fo) = sum of the outputs. 2. The condition is VI = GND to VCC.

Notes 1. Please consult the most recently issued data sheet before initiating or completing a design. 2. The product status of the device(s) described in this data sheet may have changed since this data sheet was published. The latest information is available on the Internet at URL http://www.semiconductors.philips.com. 3. For data sheets describing multiple type numbers, the highest-level product status determines the data sheet status. DEFINITIONS Short-form specification The data in a short-form specification is extracted from a full data sheet with the same type number and title. For detailed information see the relevant data sheet or data handbook. Limiting values definition Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 60134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability. Application information Applications that are described herein for any of these products are for illustrative purposes only. Philips Semiconductors make no representation or warranty that such applications will be suitable for the specified use without further testing or modification. DISCLAIMERS Life support applications These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury. Philips Semiconductors customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify Philips Semiconductors for any damages resulting from such application. Right to make changes Philips Semiconductors reserves the right to make changes in the products including circuits, standard cells, and/or software described or contained herein in order to improve design and/or performance. When the product is in full production (status ‘Production’), relevant changes will be communicated via a Customer Product/Process Change Notification (CPCN).
