Part Name(s) : HD74HC563 HD74HC573
Hitachi -> Renesas Electronics
Hitachi -> Renesas Electronics
Description : Octal Transparent Latches (with 3-state Outputs)

Description

When the latch enable (LE) input is high, the Q Outputs of HD74HC563 will follow the inversion of the D inputs and the Q Outputs of HD74HC573 will follow the D inputs. When the latch enable goes low, data at the D inputs will be retained at the Outputs until latch enable returns high again. When a high logic level is applied to the output control input, all Outputs go to a high impedance state, regardless of what signals are present at the other inputs and the state of the storage elements.



Features

•  High Speed Operation: tpd (Data to Q, Q) = 11 ns typ (CL= 50 pF)

•  High Output Current: Fanout of 15 LSTTL Loads

•  Wide Operating Voltage: VCC= 2 to 6 V

•  Low Input Current: 1 µA max

•  Low Quiescent Supply Current: ICC(static) = 4 µA max (Ta = 25°C)

Description : Octal Transparent Latches with Three-State Outputs

DESCRIPTION
The UT54ACS373 and the UT54ACTS373 are 8-bit Latches with three-state Outputs designed for driving highly capacitive or relatively low-impedance loads. The device is suitable for buffer registers, I/O ports, and bidirectional bus drivers.
The eight Latches are Transparent D Latches. While the enable (C) is high the Q Outputs will follow the data (D) inputs. When the enable is taken low, the Q Outputs will be latched at the levels that were set up at the D inputs.
An output-control input (OC) places the eight Outputs in either a normal logic state (high or low logic levels) or a high-impedance state. The high-impedance third state and increased drive provide the capability to drive the bus line in a bus-organized system without need for interface or pull-up components.
The output control OC does not affect the internal operations of the Latches. Old data can be retained or new data can be entered while the Outputs are off.
The devices are characterized over full military temperature range of -55°C to +125°C.

FEATURES
❐ 8 Latches in a single package
❐ Three-state bus-driving true Outputs
❐ Full parallel access for loading
❐ 1.2μ CMOS
   - Latchup immune
❐ High speed
❐ Low power consumption
❐ Single 5 volt supply
❐ Available QML Q or V processes
❐ Flexible package
   - 20-pin DIP
   - 20-lead flatpack
❐ UT54ACS373 - SMD 5962-96588
❐ UT54ACTS373 - SMD 5962-96589
